Lithium-Ion Batteries Can Self-Heal

if you charge/discharge them fast enough. No joke, some scientists have discovered that if they increase the rate of charge/discharge, the dendrites that form on the lithium end of the battery basically melt, reducing the risk of a short circuit and making the battery last longer. Sounds funny since too-fast charging of car batteries increases the risk of dendrites but that's tech for you. Could have huge implications for EVs.
