- Applying constant physical pressure can double the lifespan of lithium-ion batteries.
- Pressure must be in a 'Goldilocks' zone (about 12.5 bar) to prevent failures like lithium plating or cathode cracking.
- Using pneumatic bellows to maintain pressure avoids the need for specialized chemistry or materials.
- Extended battery life could reduce recycling needs and environmental impacts from mining raw materials.
- The technology, currently lab-tested, has been patented and could benefit the EV and second-hand markets.
