Breakthrough Solid State Battery

Battery technology has come a long way and has an even longer way to go. Subject Zero Science explains a recent innovation from Samsung. Samsung research was led by Yong-Gun Lee for an All-Solid-State-Battery (ASSBs). Their goal was to eliminate dendrites formation and increase coulombic efficiency. To do that they sandwiched layers of Lithium Nickel-Cobalt-Manganese-Oxide […]
