Tree-Based Batteries: A Sustainable Energy Storage Solution

News

Tree-Based Batteries: A Sustainable Energy Storage Solution

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?

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⁺).

The Power of Lithium Batteries: Benefits and Advantages — 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.

High temperatures are detrimental to lithium-ion batteries for a couple of reasons:

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.
