Not all dead batteries can be revived. If the battery is truly damaged, it’s best to dispose of it properly.
Is it Possible to Revive a Dead Lithium-Ion Battery?
Leave it on the charger: Sometimes a completely drained battery won’t be recognized by a charger at first. Leave it for an extended period (20 minutes or more) to see if it starts charging slowly.
Use a special charger: Some batteries have a “revive” function for deeply discharged batteries.
Important safety precautions:
Never force a battery to charge. Stop and dispose of it properly if it doesn’t respond after a reasonable time.
Monitor the battery temperature closely. If it gets hot, stop charging immediately.

Why is lithium the best for batteries?
Impact of Lithium’s Lightweight Property on Battery Performance
Because lithium is so lightweight, it allows for several advantages in battery design:
Portable electronics: Lithium-ion batteries are perfect for powering laptops and phones because they can pack a lot of energy into a small and lightweight package.
Longer battery life: Since lithium batteries weigh less, more battery capacity can be added to a device without significantly increasing its weight. This translates to longer battery life for our devices.
Increased efficiency in electric vehicles: The lightweight property of lithium batteries is crucial for electric vehicles. By reducing the weight of the battery pack, the overall weight of the vehicle is decreased, which in turn improves the vehicle’s range and efficiency.
Electrochemical powerhouse: Compared to other elements, lithium offers the highest electrochemical potential. This essentially means it can store more energy relative to its weight. More energy in a smaller package translates to longer battery life for our devices.
Why is lithium the best for batteries?
Lithium’s title of “electrochemical powerhouse” in batteries stems from its exceptional ability to store energy through a concept called electrochemical potential.
Here’s a breakdown:
Electrochemical Potential: This refers to the tendency of a material to undergo an electrochemical reaction, like losing or gaining electrons, and release energy in the process. A higher electrochemical potential signifies a greater energy release during the reaction.
Lithium’s Advantage: Compared to most other elements used in batteries, lithium boasts the highest electrochemical potential. Think of it as having a much higher “voltage hill” to climb compared to other elements. When lithium atoms lose an electron (oxidation), they release a significant amount of energy.
Energy Storage in Batteries: In rechargeable lithium-ion batteries, this released energy is harnessed during discharge. Lithium atoms at the anode (negative electrode) lose an electron and become positively charged ions (Li+). These ions travel through the electrolyte to the cathode (positive electrode). This movement of electrons creates a current that powers our devices.
High Energy Density: Due to its high electrochemical potential, lithium batteries can store more energy per unit weight (or volume) compared to other battery chemistries. This translates to batteries that can power our devices for longer durations.
Compact and Powerful: The combination of high energy density and lightweight nature allows lithium-ion batteries to be compact and powerful, making them ideal for portable electronics.
Why is lithium the best for batteries?
These two properties come together to make lithium-ion batteries the best option for most rechargeable gadgets we use today. They also offer other advantages like high efficiency, fast charging, and minimal maintenance.
Though lithium is king for now, researchers are always on the lookout for the next best thing. So, who knows, maybe there’ll be a new battery champion in the future!
Traditionally, copper is preferred for transformers due to its superior conductivity.
Aluminium offers a lighter weight and lower cost alternative.
Su-vastika is looking to see if Aluminium can perform well enough in their inverters.
Selection Process
The choice between copper and aluminum depends on the inverter’s duty cycle.
Key transformer specifications are identified.
A thermal test is conducted to see if the transformer can handle the expected load.
Why Compare Copper and Aluminium? A Detailed Analysis
Important Test Parameters
Primary Voltage: This is varied to assess transformer behavior under different load conditions. Specific tests like ratio polarity, and excitation current are performed based on the applied voltage. In transformer testing, the primary voltage refers to the controlled voltage applied to the transformer’s primary winding. It’s not necessarily the same voltage the transformer is rated for, but rather a variable used to evaluate its performance under different conditions.
Here’s a breakdown of the primary voltage’s role in transformer testing:
Varied Voltage: The primary voltage can be adjusted during testing to simulate how the transformer would behave under different load conditions. This helps identify weaknesses or limitations in its operation at various power levels.
Specific Tests: The specific value of the primary voltage used depends on the type of test being conducted. Here are some common examples:
Ratio and Polarity Tests: A controlled voltage is applied to the primary winding to measure the accuracy of the voltage transformation ratio between the primary and secondary windings. This test also verifies the polarity of the output voltage on the secondary side.
Excitation Current Test: A low voltage is applied to the primary to measure the current drawn by the transformer’s primary winding. This helps assess the efficiency of the transformer’s magnetic circuit, as this current is used to establish the magnetic field but doesn’t do any real work.
Why Compare Copper and Aluminium? A Detailed Analysis
2. Secondary Voltage: Plays a critical role in inverter operation (boosting 12V to 220V or vice versa, and charging 220V to 12V).
The test parameter of Secondary Voltage for a transformer, especially in the context of inverters, plays a critical role in evaluating its performance during voltage conversion. Here’s a breakdown of its significance:
Understanding Secondary Voltage:
In a typical transformer, the secondary voltage is the output voltage obtained after manipulation (usually step-up or step-down) from the applied primary voltage based on the turn ratio.
Secondary Voltage in Inverter Transformers:
Inverter transformers deal with bi-directional DC-AC and AC-DC conversion, making the role of secondary voltage slightly different.
It’s not the sole determinant of output voltage, but it does influence it.
Key functionalities of Secondary Voltage in Inverter Transformers:
Boost Mode (12V DC to 220V AC):
In this mode, the secondary voltage acts as the increased AC output voltage.
The transformer acts as a step-up transformer due to the higher number of turns in the secondary coil compared to the primary.
Charging Mode (220V AC to 12V DC):
The transformer’s role here is less straightforward.
The rectified AC voltage (after passing through a rectifier circuit) might still be higher than the desired 12V output.
The transformer can play two roles in this stage:
Step-Down Transformer: If needed, a lower secondary-to-primary voltage ratio can further reduce the voltage before it reaches the final regulation stage.
Isolation: It isolates the high-voltage AC input from the lower-voltage DC output, improving safety and reducing electrical noise.
Why Compare Copper and Aluminium? A Detailed Analysis
Factors Affecting Secondary Voltage:
Turn Ratio: The main determinant of voltage conversion. A higher ratio (more secondary turns) leads to a higher secondary voltage.
Transformer Losses: Energy is lost within the transformer due to core and copper losses. This can cause a slight reduction in the available output voltage compared to the ideal voltage based solely on the turn ratio.
Testing Secondary Voltage:
During testing, the secondary voltage is measured under various load conditions to assess the transformer’s ability to maintain a stable output voltage.
This helps identify potential voltage drops or regulation issues under different operating scenarios.
3. Turn Ratio: This ratio between primary and secondary windings determines the voltage conversion.
4. Primary No-load Current: This current is essential for the magnetic field but contributes to power loss (reduced efficiency).
Why Compare Copper and Aluminium? A Detailed Analysis
Techniques to reduce it include high-quality core materials and optimized design.
Secondary No-load Current: Represents transformer losses within the inverter circuit, impacting overall efficiency.
Output Voltage Sense: This circuit monitors and regulates the inverter’s output voltage for accuracy, protection, and efficiency.
Primary and Secondary Winding Resistances:
Affects power loss due to heat generation, reducing efficiency.
Wire gauge and number of turns are factors affecting resistance.
Primary and Secondary Winding Inductances:
Primary: Stores energy, helps maintain current flow, and affects resonant frequency.
Secondary:
Limits current surge during switching.
Affects energy transfer efficiency.
Smooths rectified AC waveform during buck mode (220V to 12V).
Phase Neutral Sequence and Neutral on the AC side:
These depend on the inverter design and how it connects to the AC system.
Power Loss: Both inverter and transformer contribute to power loss.
Inverter losses include conduction and switching losses.
Transformer losses include iron losses (hysteresis and eddy current).

Tree-Based Batteries: A Sustainable Energy Storage Solution:- Finland-based Stora Enso, one of the world’s largest owners of private forests, has a sustainable solution to the world’s increasing demand for energy storage: batteries made from trees. In partnership with Swiss battery maker Altris, Stora Enso is exploring using Lignode, a potential replacement for graphite in batteries.
With the world rapidly switching to cleaner sources of energy through solar and wind farms, there is an increased demand for solutions that can store excess energy generated on sunny or windy days.
Lithium-based batteries are the most energy-dense solutions we have. Still, the supply chain for making these batteries is tilted heavily in favor of China. Countries in the West completely depend on China to secure their energy transition, prompting a change in how energy is stored.
This passage describes an innovative partnership between Stora Enso, a major forest owner, and Altris, a battery developer, to create a sustainable solution for energy storage: batteries made from trees.
Here’s a breakdown of the key points:
The Problem:
The rise of solar and wind power is growing demand for energy storage.
Reliance on China for lithium-ion batteries, a critical component for storing energy and powering electronics.
The Alternative:
Sodium-ion batteries: Developed by Altris, these batteries offer a potential replacement for lithium-ion batteries and can be made with abundant sodium.
Lignode: Developed by Stora Enso, this bio-based material from tree byproducts (lignin) can replace graphite in battery anodes.
Benefits:
Reduced reliance on China: Creates a European supply chain for battery components.
Sustainability: Utilizes a renewable resource (trees) and reduces reliance on mined materials.
Potential for wider application: Lignode could be used in both lithium-ion and sodium-ion batteries.
Alternate energy storage solutions
Interesting Engineering has previously reported on how companies and even European governments are building large-scale energy storage solutions that do not use lithium. However, lithium-based batteries are also core components of technological advances such as mobile phones, laptops, and even electric cars.
Switzerland-based Altris develops sodium-based batteries, a potential replacement for lithium batteries. Made using abundantly available sodium, these batteries and other similarly innovative tech can help the West develop its own supply chain.
A spin-off from Uppsala University, Altris can develop cathodes, electrolytes, battery cells, and factory blueprints for commercial-scale battery production, making it ideal for developing a new type of battery from trees.
Batteries from trees
Stora Enso uses its forest reserves to manufacture pulp, of which lignin is a by-product. A naturally occurring polymer, lignin makes up to 30 percent of a tree and is abundantly available.
Lignin also contains carbon, which makes it suitable for making the anode or the positive electrode in a battery, whether based on lithium or sodium ions. Stora Enso developed the tech at its pilot plant in Kotka, Finland, and refers to it as Lignode.
Currently, anodes are made from graphite, whose supply is controlled by China. By using a material that is a by-product of another industrial process, the companies aim to set up a more stable and consistent supply chain for the production of anodes in Europe.
“Bio-based materials are key to improving the sustainability of battery cells,” said Juuso Konttinen, Senior Vice President & Head of Biomaterials Growth at Stora Enso. “With Lignode having the potential to become the most sustainable anode material in the world, this partnership with Altris aligns perfectly with our common commitment to support the ambition on more sustainable electrification.”
“At Altris, we strive to establish a local supply chain and leverage abundant and clean materials to develop sodium-ion batteries,” said Björn Mårlid, CEO of Altris said in a press release.
“Therefore, it’s exciting to team up with Stora Enso and take part in their establishment of a Europe-based tree-to-anode supply chain. We are looking forward to the partnership evolving over the coming years, with the aim to commercialise the world’s most sustainable battery.”
Why do lithium batteries lose maximum power over time?
Lithium-ion batteries lose maximum power (or capacity) over time due to two main factors: chemical reactions within the battery and temperature.
Chemical reactions: During charging and discharging cycles, lithium ions move between the anode and cathode. Over time, some of these ions become trapped or form unwanted compounds, reducing the number available for future movement. This translates to a reduced capacity to store and deliver power.
Lithium-ion batteries rely on a dance of electrons and lithium ions (Li+) between two electrodes: the anode and the cathode. This movement is based on a concept called redox reactions, short for reduction-oxidation. Here’s a breakdown of the chemical reactions during charging and discharging:
Why do lithium batteries lose maximum power over time?
Why do lithium batteries lose maximum power over time?
Discharging (Using the Battery):
Oxidation at the Anode:Lithium atoms at the anode lose an electron, becoming positively charged lithium ions (Li+). This can be represented as: Li -> Li+ + e- (electron)
Lithium Ion Movement: The Li+ ions travel through a special separator to the cathode through a liquid or solid electrolyte solution.
Reduction at the Cathode: The cathode material accepts the Li+ ions and the electrons from the external circuit. This recharges the cathode and allows it to store energy. The specific reaction at the cathode depends on the cathode material, but it generally involves the reduction of a metal ion (e.g., Co⁴⁺) to a lower oxidation state (e.g., Co³⁺).
Why do lithium batteries lose maximum power over time?
Suvastika Lithium battery
Why do lithium batteries lose maximum power over time?
Charging (Re-filling the Battery):
Reverse Reactions: When you plug in the battery, the current flow reverses. The applied voltage forces the Li+ ions to flow back from the cathode to the anode. Electrons from the charger flow through the external circuit and into the anode.
Lithium Plating: Ideally, all the Li+ ions return to the anode. However, some may get stuck on the cathode or form unwanted compounds. This reduces the number of available ions for future use.
Overall: The back-and-forth movement of Li+ ions and electrons between the electrodes is what generates electricity during discharge and stores energy during charging. However, the side reactions and degradation of materials over time lead to a gradual decrease in the battery’s capacity.
Temperature: Extreme temperatures, especially heat, can accelerate the breakdown of the electrolyte, the material that shuttles ions between the electrodes. This breakdown also reduces the battery’s ability to hold a charge.
Accelerated Chemical Reactions: Heat acts like a catalyst, speeding up the natural chemical reactions happening within the battery. This includes the breakdown of the electrolyte, the solution that shuttles lithium ions between electrodes. As the electrolyte degrades, it becomes less efficient at its job, hindering the movement of ions and reducing the battery’s ability to hold a charge.
Increased Risk of Thermal Runaway: Lithium-ion batteries generate some heat during normal operation. At high temperatures, this internal heat generation rises. The problem is that the chemical reactions that store energy are also exothermic, meaning they release heat. In a dangerous scenario, this can create a vicious cycle. As the battery gets hotter, the reactions speed up, generating even more heat. If this heat cannot be dissipated effectively, it can lead to thermal runaway.
Thermal runaway is a cascading event where the battery’s temperature rises uncontrollably. This can cause the battery to vent flammable electrolytes, rupture, or even explode. While modern lithium-ion batteries have safety features to prevent this, extreme heat significantly increases the risk.
Here’s an analogy: Imagine the battery as a container with a chemical reaction happening inside. Normally, this reaction produces a small amount of heat, like a candle. High temperatures are like turning up the heat in the room. This speeds up the reaction, making it burn hotter (more heat generation). If not controlled, the reaction could become like a fire, burning out of control (thermal runaway).
To summarize, high temperatures stress lithium-ion batteries by accelerating their degradation and raising the risk of thermal runaway. Both factors contribute to reduced battery performance and lifespan.
In simpler terms, imagine the battery as a container for ping pong balls (lithium ions). Over time, some balls get stuck or lost, and heat can damage the container itself. This means there’s less space for balls to move around, reducing the overall capacity.

Lithium batteries can store more energy and have a longer lifespan compared to lead-acid batteries. This means they can provide backup power for a longer duration during a power outage.
More stored energy, longer backup:
Capacity: Lithium ion batteries can pack more usable energy into a smaller volume compared to lead-acid batteries. This means a lithium battery with the same size as a lead-acid battery can provide more power backup during an outage.
Depth of discharge: Lithium ion batteries allow for a higher depth of discharge (DOD) compared to lead-acid batteries. DOD refers to the percentage of a battery’s capacity that can be safely used before needing a recharge. For example, a lead-acid battery might only allow a 50% DOD to preserve its lifespan, while a lithium ion battery might safely reach 80% DOD. This translates to more usable energy from the lithium battery during a power cut.
Fewer replacements, lower overall cost:
Lifespan: Lithium ion batteries typically have a longer lifespan compared to lead-acid batteries. They can go through many more charge and discharge cycles before needing replacement. This translates to fewer battery replacements over time, reducing overall costs.
Less maintenance: Lithium ion batteries require minimal maintenance compared to lead-acid batteries. Lead-acid batteries need to be checked for electrolyte levels periodically, which requires topping them off with distilled water. Lithium ion batteries are sealed units and don’t require such maintenance.
Can we use a lithium battery for an inverter?
Faster charging:
Lithium batteries generally charge faster than lead-acid batteries, allowing you to be prepared for the next power cut quickly.
Increased Power Availability: With faster charging, you can potentially use a smaller lithium battery bank and rely on quicker recharge cycles to meet your power needs.
How it Works (Generally):
Standard vs. Fast Charging: Regular lithium-ion battery charging involves two stages: constant current and then constant voltage. Fast charging introduces a third stage with a higher current early on, speeding up the initial charging phase.
Inverter’s Role: Some inverters are designed for fast-charging lithium batteries. These inverters will have a built-in fast charging profile that regulates the current and voltage throughout the charging cycle.
Safety Considerations:
Heat Generation: Faster charging generates more heat, which can stress the battery and reduce its lifespan. The inverter’s fast charging profile should manage heat generation to avoid overheating.
Battery Chemistry: Not all lithium-ion battery chemistries are created equal. Some are better suited for fast charging than others. Ensure your lithium battery is designed for the faster charging rates your inverter provides.
Important Points:
Not Universally Applicable: Not all inverters are equipped with fast-charging lithium batteries. Check your inverter’s specifications to see if it supports this feature.
Battery Compatibility: As mentioned earlier, the lithium battery you use needs to be compatible with the inverter’s fast charging profile. Using an incompatible battery can damage the battery or the inverter.
Lower self-discharge rate:
Self-discharge refers to the gradual loss of stored energy in a battery even when it’s not connected to anything. Lithium-ion batteries have a distinct advantage here compared to other rechargeable batteries, like lead-acid. Let’s break down how this impacts using a lithium-ion battery with an inverter
Slow Internal Reactions: Compared to other battery chemistries, lithium-ion experiences minimal internal chemical reactions when idle. This means less energy is lost through these background processes.
Stable Electrolyte: The electrolyte, the medium for ion flow within the battery, is more stable in lithium-ion batteries. This stability reduces unwanted reactions that can lead to self-discharge.
Can we use a lithium battery for an inverter?
Benefits for Inverter Use:
Ready Power During Outages: With a lower self-discharge rate, a lithium-ion battery for your inverter will hold its charge for longer periods when not in use. This ensures you have more reliable backup power available during unexpected outages.
Less Frequent Recharging: Since the battery loses charge slower, you won’t need to recharge it as often when it’s not powering anything. This translates to convenience and maintaining a fuller battery most of the time.
The Inverter’s Role:
An inverter itself doesn’t affect the battery’s self-discharge rate. However, since the inverter draws power from the battery when supplying AC electricity, it’s important to consider the inverter’s standby power consumption. Ideally, you want an inverter with a low standby draw to minimize overall power drain on the battery.
In essence, the combination of a lithium-ion battery’s lower self-discharge and an inverter with low standby power consumption creates a more efficient backup power system, ready whenever you need it.
Can we use a lithium battery for an inverter?
However, there are a few things to keep in mind:
Compatibility: Make sure your lithium battery is compatible with your inverter. Inverters designed for lead-acid batteries may not have the correct charging profile for lithium batteries, which can damage the battery.
Voltage: Lithium batteries typically have a higher voltage than lead-acid batteries. Ensure your inverter can handle the higher voltage of the lithium battery.
Safety: Lithium batteries require specific safety precautions when compared to lead-acid batteries. If you are not comfortable working with electronics, it is best to consult a qualified electrician to ensure safe installation.
Energy Density: Energy density refers to how much energy a battery can store in a given amount of space (volume) or weight. It’s a measure of how efficient the battery is at packing a punch.
High Energy Density: Lithium-ion batteries boast a much higher energy density, typically ranging from 250 to 670 Wh/L (Watt-hours per Liter). This means a lithium-ion battery can store a significant amount of energy in a relatively small and lightweight package.
Lead-Acid Batteries:
Lower Energy Density: Lead-acid batteries, in contrast, have a much lower energy density, typically in the range of 30 to 50 Wh/L. This translates to needing a larger and heavier battery to store the same amount of energy as a lithium-ion battery.
Portability: Since lithium-ion batteries store more energy in a smaller space, they’re perfect for powering portable electronics like laptops, phones, and cameras.
Electric Vehicles: The high energy density allows electric vehicles equipped with lithium-ion batteries to travel longer distances on a single charge compared to those using lead-acid batteries.
Weight: For the same amount of energy storage, lithium batteries weigh considerably less than lead-acid batteries. This makes them ideal for applications where weight is a major concern, like electric vehicles and portable electronics.
Charging Speed: Charging speed is a big advantage for lithium batteries over lead-acid batteries. Here’s a breakdown of why:
Lithium-ion Batteries:
Faster Charging: Lithium-ion batteries can generally accept a higher charge rate compared to lead-acid batteries. This means they can reach a full charge much quicker. Think hours for lithium-ion batteries compared to potentially 8 hours or more for lead-acid.
Lithium Chemistry: The internal chemistry of lithium-ion batteries allows for faster movement of ions during charging, leading to quicker energy intake.
Slower Charging: Lead-acid batteries require a slower and more controlled charging process. Forcing a faster charge can damage the battery and shorten its lifespan.
Crystallization Risk: During rapid charging, lead sulfate crystals can form on the lead plates within the battery. This can hinder its ability to store energy effectively.
Here’s what faster charging with lithium-ion batteries means in practical terms:
Convenience: You can recharge your phone or laptop in a shorter amount of time, keeping you connected and productive.
Electric Vehicles: Electric vehicles with lithium-ion batteries can be refueled (charged) much faster than those with lead-acid batteries, reducing downtime at charging stations.
Some additional points to consider:
Specific charging times can vary depending on the size and capacity of the battery, as well as the charger’s capabilities.
While lithium-ion batteries can handle faster charging, some manufacturers recommend slower charging rates to maximize battery life.
Lifespan: Lithium batteries typically have a longer lifespan than lead-acid batteries. They can go through more charge cycles before needing replacement.
Depth of Discharge: Lithium batteries deliver a higher percentage of their stored energy compared to lead-acid batteries. You get more usable power out of a lithium battery before needing a recharge.
Constant Power Delivery: Lithium batteries maintain a more consistent voltage output throughout their discharge cycle. Lead-acid batteries tend to weaken as they discharge.
There are some downsides to consider though. Lithium batteries are generally more expensive upfront than lead-acid batteries. Also, they require special care and handling to ensure safety.
Overall, lithium batteries offer superior performance in most applications. Their higher upfront cost can be offset by their longer lifespan and improved efficiency.
