AI helps find simple charging trick to boost battery lifespan

A simple change in how new lithium-ion batteries are charged can boost their total lifespans by 50 per cent on average – and battery manufacturers everywhere can immediately put the discovery into action. Extended battery lifespans could prove especially crucial for improving electric vehicles and energy storage for electricity grids.

“The cool thing is that we didn’t change any chemistry of the battery,” says William Chueh at Stanford University in California. “We just changed that last step in manufacturing to form the battery a little differently.”
