What is Graphene?
Graphene is a single layer of carbon atoms arranged in a hexagonal lattice, with very high electrical conductivity, strength and surface area. In batteries it is used as a conductive network in electrodes, a host for silicon and sulfur, and in supercapacitor electrodes. NanoLithium supplies graphene for battery and materials research.
