Li Batteries can grow “dendrites”, basically a tiny whisker that grows between the anode and cathode that eventually shorts the cell out. I know the old trick to restore NiCad batteries involved using a large charged capacitor across the leads, the massive dump of current would burn away any similar features shorting out the cells internals. Never heard of it being used for Li batteries, but figures that someone would give it a go!
