New lithium-ion batteries could last 20 years

Though I cannot imagine any device that wouldn’t be outdated in those 20 years, Researchers at Japan’s Eamex have discovered a technique that could dramatically extend the lifespan of lithium-ion batteries.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.
Eamex plans to ship these batteries sometime this year. Batteries like this could dramatically reduce the size of mobile devices!
