Bringing ‘Dead’ Batteries Back to Life – Researchers Extend Battery Lifetime by 30%
Islands of inactive lithium creep like worms to reconnect with their electrodes, restoring a battery’s capacity and lifespan.Researchers at the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University believe they have discovered a means to revive rechargeable lithium batteries, which might increase the range of electric cars and battery life in next-generation electronic devices.As lithium batteries cycle, small islands of inactive lithium form between the electrodes, reducing the battery’s…
