Existing EV batteries could be recharged five times faster

Overcharging a lithium-ion battery anode can lead to lithium buildup, which can break through a battery’s separator, create a short-circuit and cause catastrophic failure. That can cause the electrolyte to emit gases and literally blow up the battery, so manufacturers impose strict charging power limits to prevent it. Those limits are based on hard-to-measure internal …
