New lithium-ion batteries could last 20 years

Researchers at Japan's Eamex have discovered a technique that could dramatically extend the lifespan of lithium-ion batteries. The new approach keeps the tin inside the battery intact for much longer despite the strain caused by charging and recharging. By absorbing much of the stress through a new alloy in the tin-coated resin, the tin and the electrode structure are more stable and could last for as long as 20 years.
