Abstract:
A composite material comprising graphene or reduced graphene oxide and a polymer-derived ceramic material, such as SiOC, is provided. The composite materials can be used to construct anodes (16), which can be used in batteries (10), particularly lithium ion batteries. The anodes exhibit relatively high charge capacities at various current densities. Moreover, the charge capacity of the anodes appears exceptionally stable even after numerous charging cycles, even at high current densities.
