Straightforward fabrication of a highly branched graphene nanosheet array for a Li-ion battery anode

A new graphene-based hybrid nanostructure is designed for anode materials in lithium-ion batteries. The highly branched graphene nanosheets (HBGNs) directly grown on a copper current collector exhibited promising electrochemical performance due to their unique morphology, high electrical conductivity, large interfacial surface area, and high porosity.
