Lithium metal batteries can hold at least a 3rd more energy per pound as lithium-ion. “An EV with a state-of-the-art lithium metal battery would lose variety at a much faster rate than an EV powered by a lithium-ion battery,” Zhang said.Discharge and restIn previous work, Sayavong and his colleagues discovered that the SEI matrix starts to dissolve when the battery is idle.”Using time-lapse video microscopy, the scientists aesthetically confirmed the disintegration of recurring SEI and subsequent recovery of dead lithium throughout the resting phase.Practical applicationsThe average American driver invests about an hour behind the wheel each day, so the idea of resting your automobile battery for several hours is feasible.A normal EV may have 4,000 batteries organized in modules controlled by a battery management system, an electronic brain that keeps an eye on and controls battery efficiency.
