Graphene Oxide Nanosheets for Lithium-Metal Batteries

Lithium-metal batteries — which can hold up to ten times more charge than lithium-ion batteries — haven't been commercialized because of a fatal flaw: as the batteries charge and discharge, lithium is deposited unevenly on the electrodes. This buildup cuts the lives of these batteries too short to make them viable, and more importantly, can cause the batteries to short-circuit and catch fire.
