New discovery could lead to faster-charging and longer-range EVs

In a breakthrough for the EV industry, researchers have discovered a way to prevent a damaging and potentially dangerous side effect that can occur during fast charging: lithium plating. The phenomenon takes place when lithium ions build up on the surface of the battery’s anode (aka the negative electrode) instead of inserting themselves into it via a process called intercalation. As a result, the ions form a layer of metallic lithium which continues to grow on top of the anode. This can damage the battery, reduce its lifespan, decrease its overall performance, and cause short-circuits that could lead to fire…
