To extend a lithium-metal EV battery’s life, just drain it and let it sit, find Stanford scientists

Electrek

Stanford University researchers found that the best way to extend the life of a lithium-metal EV battery is to drain it and let it rest for a few hours.

Stanford scientists figured out why lithium metal batteries fail

Electrek

Researchers at Stanford University and the US Department of Energy’s SLAC National Accelerator Laboratory have identified what causes lithium metal batteries to short-circuit and fail – and this could help avoid the problem in future battery production.

DOE, Stanford researchers bring “dead” lithium batteries back to life

Electrek

But, a team of DOE and Stanford scientists say they’ve been able to make this “dead” li-ion reconnect, partially reversing the unwanted loss of energy capacity and extending lithium battery life by 30%. That happens because small bits of lithium can be cut off from the battery’s electrodes during the charging process.

Stanford, CMU, MIT team reviews challenges to practical implementation of solid-state Li-ion batteries

Green Car Congress

Toyota, which has been working on solid-state batteries for EVs for a number of years ( earlier post ), is in the news with a report by the Wall Street Journal that it will be ready to commercialize a solid-state battery by 2022. However, there remain a number of unresolved issues precluding commercialization at this point.
