The lithium-ion batteries found in most modern EVs and hybrids tend to lose energy capacity as they cycle (get charged, get spent, and get re-charged). That happens because small bits of lithium can be cut off from the battery’s electrodes during the charging process. 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%.
