Graphene anode material
WebDec 30, 2024 · Graphene is a carbon allotrope with a two-dimensional hexagonal structure. By altering production techniques, it can be converted into zero-dimensional fullerenes, one-dimensional carbon nanotubes, and three-dimensional graphite. As a result, graphene serves as a foundation for additional graphite compounds. WebJan 1, 2024 · Graphene and graphene-based composites as anode materials As an anode for LIBs, the theoretical capacity of pristine graphene is more than twice that of conventional graphite anode, because Li ions can be stored on both sides, edges, as well as some defect sites [15].
