Revolutionary cathode material for lithium-sulfur batteries
Researchers have made a breakthrough in Lithium-Sulfur (Li-S) battery technology by developing a revolutionary cathode material. This new material addresses some of the key challenges that have prevented Li-S batteries from being widely used.
Here’s the key takeaway:
The new cathode material is a special crystal made of sulfur and iodine. This dramatically improves electrical conductivity, a major weakness of traditional sulfur cathodes.
Another benefit is the low melting point (65°C) of this new material. This allows the battery to self-heal. During charging and discharging, electrodes can become damaged. With this new material, heating the battery to a temperature lower than a hot cup of coffee can remelt the cathode and repair these damages.
In tests, a battery made with this new cathode material showed great promise. It remained stable for over 400 charging cycles while retaining a high percentage (87%) of its capacity. This is a significant improvement over traditional Li-S batteries.
Overall, this new cathode material is a significant step towards making Li-S batteries a reality. These batteries have the potential to hold much more energy and be cheaper to produce than conventional lithium-ion batteries.
Lithium-sulfur (Li-S) batteries are a promising next-generation battery technology because they offer higher energy density and lower cost compared to conventional lithium-ion batteries. This means they could potentially store more energy and be cheaper to produce.
However, there have been challenges with Li-S batteries, such as poor conductivity of sulfur cathodes and structural damage during charging and discharging. Researchers at UC San Diego have developed a new cathode material that addresses these limitations.
Their new material is a crystal composed of sulfur and iodine. This increases the conductivity of the cathode by 11 orders of magnitude and it has a low melting point (65°C) which allows the cathode to be rehealed after charging to repair damage.
In tests, the battery made with this new cathode material remained stable for over 400 cycles while retaining 87% of its capacity. This is a significant improvement over traditional Li-S batteries.
The researchers are continuing to develop this technology but it has the potential to revolutionize batteries by offering much longer lifespans and lower costs.
Solid-state lithium-sulfur batteries are a type of rechargeable battery consisting of a solid electrolyte, an anode made of lithium metal, and a cathode made of sulfur. These batteries hold promise as a superior alternative to current lithium-ion batteries as they offer increased energy density and lower costs. They have the potential to store up to twice as much energy per kilogram as conventional lithium-ion batteries – in other words, they could double the range of electric vehicles without increasing the battery pack’s weight. Additionally, the use of abundant, easily sourced materials makes them an economically viable and environmentally friendlier choice.
However, the development of lithium-sulfur solid-state batteries has been historically plagued by the inherent characteristics of sulfur cathodes. Not only is sulfur a poor electron conductor, but sulfur cathodes also experience significant expansion and contraction during charging and discharging, leading to structural damage and decreased contact with the solid electrolyte. These issues collectively diminish the cathode’s ability to transfer charge, compromising the overall performance and longevity of the solid-state battery.
To overcome these challenges, a team led by researchers at the UC San Diego Sustainable Power and Energy Center developed a new cathode material: a crystal composed of sulfur and iodine. By inserting iodine molecules into the crystalline sulfur structure, the researchers drastically increased the cathode material’s electrical conductivity by 11 orders of magnitude, making it 100 billion times more conductive than crystals made of sulfur alone.
Study co-senior author Ping Liu, a professor of nanoengineering and director of the Sustainable Power and Energy Center at UC San Diego remarked, “We are very excited about the discovery of this new material. The drastic increase in electrical conductivity in sulfur is a surprise and scientifically very interesting.”
Moreover, the new crystal material possesses a low melting point of 65º Celsius (149º Fahrenheit), which is lower than the temperature of a hot mug of coffee. This means that the cathode can be easily re-melted after the battery is charged to repair the damaged interfaces from cycling. This is an important feature to address the cumulative damage that occurs at the solid-solid interface between the cathode and electrolyte during repeated charging and discharging.
Study co-senior author Shyue Ping Ong, a professor of nanoengineering at the UC San Diego Jacobs School of Engineering commented, “This sulfur-iodide cathode presents a unique concept for managing some of the main impediments to commercialization of Li-S batteries. Iodine disrupts the intermolecular bonds holding sulfur molecules together by just the right amount to lower its melting point to the Goldilocks zone — above room temperature yet low enough for the cathode to be periodically re-healed via melting.”
Study co-first author Jianbin Zhou, a former nanoengineering postdoctoral researcher from Liu’s research group added, “The low melting point of our new cathode material makes repairing the interfaces possible, a long sought-after solution for these batteries,” said study co-first author Jianbin Zhou, a former nanoengineering postdoctoral researcher from Liu’s research group. “This new material is an enabling solution for future high energy density solid-state batteries.”
To validate the effectiveness of the new cathode material, the researchers constructed a test battery and subjected it to repeated charge and discharge cycles. The battery remained stable for over 400 cycles while retaining 87 percent of its capacity.
“This discovery has the potential to solve one of the biggest challenges to the introduction of solid-state lithium-sulfur batteries by dramatically increasing the useful life of a battery,” said study co-author Christopher Brooks, chief scientist at Honda Research Institute USA, Inc. “The ability for a battery to self-heal simply by raising the temperature could significantly extend the total battery life cycle, creating a potential pathway toward real-world application of solid-state batteries.”
The team is working to further advance the solid-state lithium-sulfur battery technology by improving cell engineering designs and scaling up the cell format.
“While much remains to be done to deliver a viable solid-state battery, our work is a significant step,” said Liu. “This work was made possible thanks to great collaborations between our teams at UC San Diego and our research partners at national labs, academia, and industry.”

Well, twice the capacity for a year and a month for a way lower price might make a go of it. The question is how many remelts can the system stand? 2 won’t get very far but 10 or 20 would be a revolution.
There will need to be a standard setting for remelting purposes. Some coding systems as one can’t foresee an endless remelt, and to make an exchange system practical.
During operation and charging, lead acid batteries produce hydrogen and oxygen which occupies the headspace in a battery above the electrolyte. If such gasses are not vented correctly or are exposed to a source of ignition, a battery explosion can occur. For a battery to explode two elements must be present – explosive gasses, namely hydrogen and oxygen, plus a source of ignition, external or originating from within the battery

Exploding Lead-Acid Batteries: How to Stay Safe
Battery explosions occur when two key elements are present:
Explosive gases: Lead-acid batteries, during use and charging, produce hydrogen and oxygen gases that accumulate inside the battery.
Ignition source: A spark or flame can ignite this built-up gas mixture, causing an explosion.
Causes of Battery Explosion?:-
Normal Operation, Overcharging, and Faulty Systems Under normal operating circumstances, a flooded lead acid battery can maintain a hydrogen and oxygen concentration above the level where an ignition source may cause an explosion. Overcharging as a result of faulty vehicle charging systems can produce more of these gasses and as such can increase the risk of explosion. Overcharging can also increase the rate of grid corrosion breakdown of the internal battery plate and separators leading to the possibility of short circuits and explosion.
Normal operation: Even under normal conditions, lead-acid batteries can contain enough hydrogen and oxygen to explode if exposed to an ignition source.
Overcharging: Faulty charging systems can overcharge batteries, producing excessive gas and increasing the explosion risk. Overcharging can also damage internal battery components, leading to short circuits and explosions.
External ignition sources: Sparks from static electricity, open flames, cigarettes, or loose/corroded battery connections can ignite the battery gases.
Engine starting: When a battery nears its end of life and has internal damage, starting the engine can trigger a short circuit and explosion, especially if the electrolyte level is low.
Manufacturing faults: Defects in battery construction, like a poorly connected terminal post, can cause arcing and ignite the gases.
End-of-life batteries: As batteries age, the plates corrode, increasing the risk of internal short circuits and explosions. Blocked vent plugs in old batteries can also contribute.
Poor maintenance: Neglecting battery maintenance, like letting electrolyte levels drop, can expose battery plates and accelerate corrosion, raising the risk of short circuits and explosions.
Exploding Lead-Acid Batteries: How to Stay Safe
External Sources of Ignition:-
Primary sources of ignition such as static sparks, naked flames, cigarettes, and sparks caused by metal objects touching or shorting the battery terminals, loose battery connections, and corroded cables can ignite the flammable gasses built up in a battery.
Engine Starting:-
Starting the engine places a load on the battery that can trigger an explosion when there is an underlying problem. This is more likely when a battery is near its’ end of life. Both internal plate corrosion or a manufacturing fault increases the risk of a short circuit especially when the electrolyte level is low and the potential short is in the gas space.
Manufacturing Faults:-
Defects or faults in the manufacturing process can cause a battery to short circuit. For example, if the internal terminal post is not correctly fused to the external terminal lead, arcing can occur. Such a fault is detected by a complete absence of voltage with intermittent spikes up to normal voltage levels. This is a dangerous situation as just physically moving the battery can cause a short circuit. Inter-cell welds located above the electrolyte are subject to high current flow during operation and engine starting. If the weld is faulty or corroded, the surface area available for the passage of an electrical current may be reduced, generating high temperatures and breakdown of the weld leading to arcing or melting of the lead itself. Both of these conditions are rare.
End of Life:-
Batteries nearing their end of life will exhibit increased signs of grid corrosion and degradation of active material on the battery plates. This can gather in the plate separators leading to a possibility of short circuits between the battery plates. Blocked vent plugs can also cause a short circuit as the battery cell expands under pressure.
Poorly Maintained Batteries:-
Batteries that have been left in a poorly maintained state for extended periods can lead to an increased possibility of explosion. If electrolyte levels are allowed to fall exposing the top of the battery plates, they will corrode faster than the section below causing growth, the possibility of plate contact, and an increased risk of a short circuit occurring.
Regular battery care and maintenance can help reduce the risk of a battery exploding. Century Ultra Hi and Hi Performance batteries are maintenance enabled allowing electrolyte levels to be topped up, reducing the risk of explosion, and problems caused by excessive water loss, and helping maximize the life of the battery
Battery Types and Explosion Risk:-
The text categorizes different battery types based on their explosion risk:
Maintenance Free Lead-acid (highest risk): Requires maintenance but reduces the risk of exposed plates causing short circuits. Vulnerable to manufacturing faults and external ignition sources.
Maintainable lead-acid (medium risk): Offers some protection against explosions from exposed plates due to maintainable electrolyte levels. Still susceptible to external ignition sources and manufacturing faults.
AGM VRLA (low risk): Sealed design minimizes the risk of short circuits from exposed plates. Vulnerable to manufacturing faults.
GEL VRLA (low risk): Similar to AGM VRLA in design and explosion risk.

Electrolyte level: Maintain proper electrolyte level (if applicable) by topping up when necessary.
Battery testing: Test battery health using a voltmeter or hydrometer and charge as needed.
Proper charger: Use an Australian-approved charger with the correct capacity for your battery.
Avoid fast charging: Fast charging can damage batteries and increase the risk of overheating and gas buildup.
Follow charging times: Refer to the recommended charging times based on the battery’s state of discharge.

If skin or hair contact occurs, remove contaminated clothing and flush skin or hair with running water.
Basic electro-chemical processes such as using redox reactions to create a flow of electrons are the basis for how batteries work. Most batteries or cells are based on the galvanic cell. Good examples of batteries based on galvanic cells are dry cell batteries commonly used in flashlights and transistor radios; lead storage batteries which are your car batteries; and lithium-ion batteries normally found in cell phones, digital cameras, laptops, and electric vehicles. Galvanic cells contain cathodes and anodes with some form of an electron salt bridge. The cathode is negatively charged, where reduction occurs, and where electrons are gained. The opposite end of the spectrum on the battery is the anode which is positively charged and where electrons are lost. It should be noted that this is when the cell is operating. Salt bridges help facilitate the longevity of the battery and complete the circuit for the flow of electrons. Without the salt bridge electrons would not flow from cation to anion since the circuit would not be complete and a buildup of residue that collects from using the battery would render it useless as no charge would be created.
It clearly outlines the key concepts of electrochemistry involved in their operation. Here’s a breakdown of the main points:
1. Electrochemical Reactions and Galvanic Cells:
Batteries rely on redox reactions, where one element loses electrons (oxidation) and another gains them (reduction).
This electron flow creates electricity in galvanic cells.
Examples of batteries based on galvanic cells include dry cells, car batteries, and lithium-ion batteries.
2. Cathode, Anode, and Electrolyte:
The cathode (negative) attracts electrons (reduction).
The anode (positive) loses electrons (oxidation).
The electrolyte conducts electricity within the battery, replacing the historical salt bridge.
3. Voltage and Standard Reduction Potentials:
The voltage of a battery is determined by the difference in electrical potential between the anode and cathode, measured in volts.
Standard reduction potentials indicate an element’s tendency to gain or lose electrons.
Elements with high reduction potentials are good cathode materials, while those with low reduction potentials are good anode materials.
The bigger the difference between the cathode and anode’s reduction potentials, the higher the voltage of the battery.

Dry Cells
Dry cell batteries also known as the Leclanché cell are commonly used in devices such as flashlights. These batteries contain no fluid in them, hence the name dry cell. Dry cells have a graphite cathode rod in the center and a zinc anode. These are both in contact with a mixture of manganese dioxide MnO2 and carbon which contact the outside of the rod and zinc plate to help with the flow of electrons. However, as mentioned earlier batteries need to have some form of electron carrier, whether it be a salt bridge or electrolyte solution of some form. In these cells, a pasty-like substance is used which contains electrolytes, usually composed of zinc (II) chloride ZnCl2 and ammonium chloride NH4Cl. This substance is used instead of a typical aqueous, dissolved in water, electrolyte because it creates a safer and less likely to leak battery. The battery then has a thin paper spacer around the paste, cathode, and anode and is then finally enclosed in a protective coating composed of some form of steel. Generally, these cells produce around 1.5 volts of energy.

Lead Acid Storage Cells
Commonly seen in vehicles the lead storage battery is made up of six identical cells all joined together in series. Every one of the six cells is composed of a lead anode and a cathode made of lead dioxide PbO2 and both are on a metal plate that is in a sulfuric acid solution. The sulfuric acid acts as the electrolyte in this cell. If you look at your car battery these are enclosed in a plastic case. Lead storage cells output about 2.1 V per cell so in total the battery outputs around 12.6 V of energy used for starting your vehicle and running the other electronic components including but not limited to your radio. The interesting and useful part of lead cell batteries is that they can be recharged. Recharging batteries means that you run the battery through the reverse process that it normally goes through instead of the battery outputting energy, energy is inputted into the battery. This process is also called electrolysis.
The Science Behind Batteries: Basics of Electrochemistry
Lithium-Ion Cells
Powering Everyday Devices: Lithium-ion batteries are dominant in portable electronics due to their small size, light weight, and efficient recharging capabilities.
Components: They consist of a carbon-based anode (often graphite), a transition metal oxide cathode (like cobalt oxide), and a non-aqueous electrolyte in between.
Electrolyte Function: The electrolyte solution, containing a lithium salt, allows lithium ions to flow freely.
SEI Layer: A protective layer forms on the electrodes (SEI) due to the lithium salt, preventing uncontrolled electron flow but enabling lithium ion movement for the reaction.
Cathode & Anode Roles: These depend on charging/discharging. During discharge, lithium ions flow from anode to cathode, generating electricity.
Lithium Advantage: Lithium’s low reduction potential allows for high voltage output (around 3.4V) in these cells.
Degradation: Over time, the SEI layer grows, slightly reducing battery capacity.
The Science Behind Batteries: Basics of Electrochemistry
Here are some key takeaways:
Components and Materials:
Anode: Made of graphite (carbon-based) which stores lithium ions (Li+) and lithium (Li) atoms.
Cathode: Made of a transition metal oxide (like cobalt oxide CoO2) that can also store lithium ions.
Electrolyte: Non-aqueous solution (no water) containing a lithium salt (LiClO4 or LiPF6) that allows lithium ions to flow.
The SEI Layer:
A thin layer (Solid Electrolyte Interphase) forms on the electrodes during battery operation.
This layer prevents uncontrolled electron flow but allows lithium ions to pass through, enabling the battery to function.
High energy density: Pack a lot of energy in a small and lightweight package.
Rechargeable: Can be charged and discharged hundreds of times.
High efficiency: Lose minimal energy during charge/discharge cycles.
The Science Behind Batteries: Basics of Electrochemistry
Limitations:
SEI layer growth: Over time, the SEI layer can thicken, reducing battery capacity.
Safety concerns: Lithium is highly reactive, requiring careful design and handling to prevent fires.
The Science Behind Batteries: Basics of Electrochemistry
Overall:
Lithium-ion batteries are a powerful technology due to their combination of high energy density, rechargeability, and efficiency. They are a key enabler for portable electronics in the 21st century.
Understanding the Working of Lithium-Ion Batteries, The lithium-ion (Li-ion) battery is the predominant commercial form of rechargeable battery, widely used in portable electronics and electrified transportation. The rechargeable battery was invented in 1859 with lead-acid chemistry that is still used in car batteries that start internal combustion engines, while the research underpinning the Li-ion battery was published in the 1970s and the first commercial Li-ion cell was made available in 1991. In 2019, John B. Goodenough, M. Stanley Whittingham and Akira Yoshino received the Nobel Prize in Chemistry for their contributions to the development of the modern Li-ion battery.
Understanding the Working of Lithium-Ion Batteries
During a discharge cycle, lithium atoms in the anode are ionized and separated from their electrons. The lithium ions move from the anode and pass through the electrolyte until they reach the cathode, where they recombine with their electrons and electrically neutralize. The lithium ions are small enough to be able to move through a micro-permeable separator between the anode and cathode. In part because of lithium’s small atomic weight and radius (third only to hydrogen and helium), Li-ion batteries are capable of having a very high voltage and charge storage per unit mass and unit volume.
Li-ion batteries can use a number of different materials as electrodes. The most common combination is that of lithium cobalt oxide (cathode) and graphite (anode), which is used in commercial portable electronic devices such as cellphones and laptops. Other common cathode materials include lithium manganese oxide (used in hybrid electric and electric automobiles) and lithium iron phosphate. Li-ion batteries typically use ether (a class of organic compounds) as an electrolyte.
Lithium ions are stored within graphite anodes through a mechanism known as intercalation, in which the ions are physically inserted between the 2D layers of graphene that make up bulk graphite. The size of the ions relative to the layered carbon lattice means that graphite anodes are not physically warped by charging or discharging, and the strength of the carbon-carbon bonds relative to the weak interactions between the Li ions and the electrical charge of the anode make the insertion reaction highly reversible.

Understanding the Working of Lithium-Ion Batteries
Compared to other high-quality rechargeable battery technologies (nickel-cadmium, nickel-metal-hydride, or lead-acid), Li-ion batteries have several advantages. They have one of the highest energy densities of any commercial battery technology, approaching 300 watt-hours per kilogram (Wh/kg) compared to roughly 75 Wh/kg for alternative technologies. In addition, Li-ion cells can deliver up to 3.6 volts, 1.5-3 times the voltage of alternatives, which makes them suitable for high-power applications like transportation. Li-ion batteries are comparatively low maintenance and do not require scheduled cycling to maintain their battery life. Li-ion batteries have no memory effect, a detrimental process where repeated partial discharge/charge cycles can cause a battery to ‘remember’ a lower capacity. Li-ion batteries also have a low self-discharge rate of around 1.5-2% per month and do not contain toxic lead or cadmium.
Understanding the Working of Lithium-Ion Batteries
High energy densities and long lifespans have made Li-ion batteries the market leader in portable electronic devices and electrified transportation, including electric vehicles (EVs) like the Nissan Leaf and the Tesla Model S as well as the hybrid-electric Boeing 787. In terms of decarbonizing our economy’s energy use, Li-ion technology has its greatest potential in EVs and electrified aviation.

What are some disadvantages of Li-ion batteries?
Not only are lithium-ion batteries widely used for consumer electronics and electric vehicles, but they also account for over 80% of the world’s 99 gigawatt-hours (GWh) of energy storage deployed today. However, energy storage for a 100% renewable grid brings in many new challenges that cannot be met by existing battery technologies alone.
First, more than 10 terawatt-hours (TWh) of storage capacity is needed, and multiplying today’s battery deployments by a factor of 100 would cause great stress to supply chains of rare materials like lithium, nickel, and cobalt. Second, large-scale, long-duration energy storage requires extremely low costs — significantly less than $100/kWh, or more than twice as cheap as today’s state-of-the-art battery technologies — and more than 20 years of reliable service life. Furthermore, scaling up conventional battery energy storage systems from kWh to MWh or GWh presents a serious challenge for robust electric and thermal management.
For the U.S. to store 8 hours of electricity, it would need to deploy terawatt-hours of batteries, which would cost trillions of dollars at today’s prices, while 6 weeks of seasonal heating would require petawatt-hours (thousands of TWh) of storage. Therefore, a 100% clean energy future requires not only the development of low-cost battery technologies using environmentally friendly, earth-abundant materials but also new storage strategies using a combination of electrochemical, chemical, thermal, and mechanical mechanisms.

CEI Research Highlights
A major focus of CEI energy storage research is the development of novel materials to improve battery performance. Some CEI researchers develop substitutes for the components of a conventional Li-ion battery, such as silicon-based anodes instead of graphite. Others work to improve upon well-developed battery components by building in micro- and nano-scale architectures that can improve the speed and efficiency of charge cycles, with physical features that are smaller than the width of a human hair. CEI researchers are also exploring alternative chemistries to Li-ion that might be suitable for a specific application.
For example, chemical engineering (ChemE) professor Vincent Holmberg and his research group are developing and investigating alloying materials for Li-ion batteries. Materials like silicon, germanium, and antimony react with Li ions to form alloys, which results in greater capacities than graphite anodes that rely on intercalating Li ions between layers of graphene. However, alloying materials experience greater changes in physical volume that can deform the electrode and lead to performance losses or failure. However by introducing a nanostructure into the alloying material, the Holmberg group can reduce the stress and strain on the electrode from the charge and discharge reactions. The physical morphologies of the electrodes can affect the battery’s ability to hold and transfer charge, as can any chemical interactions between the lithium ions and the surface of the electrodes.
Developing a deeper understanding of reversible “conversion” charge-discharge reactions is key to deploying new battery chemistries with higher theoretical energy densities, such as lithium-sulfur. With sulfur’s abundance and relatively low atomic weight, Li-S batteries could be cheaper and lighter than Li-ion batteries with graphite anodes, but achieving this high energy density simultaneously with long cycle life remains a grand challenge for energy storage scientists and engineers. Lithium-based devices often fail due to the formation of “dendrites” of lithium metal growing on the anodes like tree roots through a sidewalk.
Materials science & engineering professor Jun Liu investigates the degradation mechanisms of Li metal with Li-nickel manganese cobalt (NMC) cathodes in pouch cells and has presented fundamental linkages among Li thickness, electrolyte depletion, and the structural evolution of solid–electrolyte interphase layers. Meanwhile, CEI director and ChemE professor Dan Schwartz and his group are working on computational models of Li-S systems that can be corroborated by experimental results. Liu is the director of the Battery500 Consortium — led by the Pacific Northwest National Laboratory (PNNL) and including Schwartz on the executive committee — which aims to develop next-generation EV batteries with energy densities approaching 500 watt-hours per kilogram, double the industry standard.
With technological progress in mobile electronics driving demand for denser batteries, engineers are also employing three-dimensional (3D) electrode architectures and additive manufacturing methods to rapidly fabricate battery prototypes with improved performance. Research led by mechanical engineering (ME) professor Corie Cobb in her Integrated Fabrication Lab focuses on how 3D electrode architectures can improve many aspects of battery performance. Furthermore, with the state-of-the-art prototyping and testing capabilities at the Washington Clean Energy Testbeds, ME and materials science & engineering (MSE) professor J. Devin MacKenzie’s group and the Holmberg group are collaborating to structurally engineer antimony alloying electrodes. Special inkjet printers allow these engineers to build 3D electrode architectures with droplets just microns across, while one of the only open-access, high-throughput roll-to-roll electronics printers in the world enables rapid iteration at commercial scales. The Testbeds, at which MacKenzie is the technical director, also house top-of-the-line microscopes and battery testing equipment to validate new electrode designs.
Understanding the Working of Lithium-Ion Batteries
CEI researchers are also creating physical, mathematical, and computational models to evaluate how batteries operate and fail. These models can help optimize battery performance and charge/discharge cycles and predict dangerous battery failures. The Schwartz group is advancing diagnostics for Li-ion batteries to obtain data on day-to-day operations and battery health, a dynamic alternative to a physical “autopsy” at the end of the device’s use. Along with physics-based models of battery systems, these diagnostic tools can detect signs of degradation in real-time, allowing users to modify their operations to extend battery lifespans. Furthermore, researchers in the Schwartz group use these models to project second lives for batteries that have degraded beyond EV performance standards, such as in solar-powered microgrids.
With the UW “Hyak” supercomputer, researchers can simulate molecules and their kinetic and thermodynamic interactions to understand electrochemistry from a perspective that is not afforded to experimental techniques.
Understanding the Working of Lithium-Ion Batteries
CEI researchers also use direct imaging techniques like X-ray spectroscopy to understand the inner workings of batteries. Professor Jerry Seidler’s lab has developed a method to perform X-ray absorption near-edge structure (XANES) spectroscopy on the benchtop. The technique provides relatively detailed measurements of certain characteristics of a battery’s internal state, without having to open it and thus disrupt the system. Previously, XANES could only be accomplished with an extremely high radiative flux, from instruments such as a synchrotron. These are extremely large and expensive facilities, costing up to $1 billion, and often only available to the public via federal labs with months-long waiting lists. But as optoelectronic technologies have evolved, the Seidler lab spun out a company to prototype a $25,000 benchtop instrument that can mimic the measurements taken at a synchrotron. The EasyXAFS already enables scientists to obtain XANES measurements in hours, which can accelerate the innovation cycle for batteries and other energy-related materials and devices.
Understanding the Working of Lithium-Ion Batteries
Meanwhile, chemistry professor Cody Schlenker and his group investigate the fundamental chemistry of interfaces within energy storage systems to gain a deeper understanding of electrochemical processes.

Reliance unveils swappable, multipurpose batteries for EVs
Reliance Industries, a major Indian company known for oil refining, is entering the clean energy market with a new battery technology. They unveiled swappable batteries that can be used for two purposes:
Battery Storage: EVs rely on a large rechargeable battery pack, typically Lithium-ion based, to store electrical energy. This battery acts like the fuel tank in a gasoline car.
Electric Motor: Instead of an internal combustion engine, EVs use one or more electric motors. These motors convert the electrical energy from the battery into power to drive the wheels.
Charging: To refill the battery, EVs need to be plugged into a charging station. These stations can be found at homes, workplaces, public locations, or special charging networks. The charging time depends on the battery size and the type of charger used.
Regenerative Braking: During braking or downhill driving, EVs can recapture some energy. The electric motor acts as a generator, converting the car’s momentum back into electricity and topping off the battery.
Here’s a benefit of EVs related to powering them:
Reduced Emissions: Since EVs don’t burn gasoline, they produce zero tailpipe emissions, contributing to cleaner air. However, their environmental impact depends on the source of electricity used to charge them. Ideally, renewable sources like solar or wind power would be used for maximum benefit.
Powering household appliances: By connecting the battery to an inverter, it can provide electricity to a home’s appliances during power outages or other situations,
Household appliances are typically powered by electricity from the grid. When you plug in an appliance, electricity flows through a cord and into the appliance. Inside the appliance, the electricity is used to power various components, depending on the appliance’s function.
Here are some examples of how electricity is used to power common household appliances:
Appliance
How Electricity is Used
Refrigerator
A compressor circulates cool air.
Toaster
Coils heat up to radiate heat to toast bread.
Washing machine
A motor spins the drum and pumps water.
In addition to these examples, electricity is used to power a wide variety of other household appliances, including ovens, microwaves, dishwashers, clothes dryers, vacuum cleaners, televisions, computers, and more. The way that electricity is used to power each appliance varies depending on the specific function of the appliance. However, the basic principle is the same: electricity flows through the appliance and is used to power various components.
This multipurpose design aims to give consumers more flexibility and potentially reduce costs.
Here are some additional points to note:
Reliance plans to build a network of battery-swapping stations where users can quickly replace a depleted battery with a charged one.
The company also intends to sell rooftop solar panels, allowing homeowners to recharge the batteries with renewable energy.
The exact launch date for these batteries is not yet announced.
Overall, this initiative is part of Reliance’s larger strategy to invest in clean energy solutions and move away from its reliance on fossil fuels.
Indian oil refining giant Reliance Industries showcased its swappable and multipurpose battery storage technology for electric vehicles (EVs) on Wednesday, as it makes a big push on clean energy.
Reliance, led by billionaire Mukesh Ambani, displayed removable and swappable batteries for EVs that can also be used to power household appliances through an inverter at a renewable energy exhibition.
The idea is that a person can use one battery for mobility and powering appliances at home, company executives at the event said, requesting not to be quoted as they are not authorized to speak with media.
The batteries can be swapped at Reliance’s battery swap stations or re-charged by households using rooftop solar panels, which also it plans to sell, the executives added. The executives did not clarify when the company planned to start selling these batteries.
The development of battery storage solutions is a part of Reliance’s bigger $10 billion green push towards clean energy projects. The company aims to cut dependence on its mainstay oil-to-chemical business and be net zero carbon by 203
