چکیده

A foam-like graphene material can be prepared by freeze drying and thermal reduction of graphene oxide suspensions. The graphene foam has a much higher capacity then conventional graphite anode, and it possesses better rate capability comparing with powderlike graphene active materials reported previously. The influence of the annealing temperature on the charge-discharge performance of graphene foam has been investigated.

High quality graphitized graphene as an anode material for lithium ion batteries.

High quality graphitized graphene has been successfully synthesized by solid-exfoliation of graphite and a subsequent wet chemical process. The as-obtained graphene exhibits charge-discharge behaviour quite different from that of reduced graphene oxide and shows enhanced cycling and rate performance compared with commercial mesocarbon microbeads (MCMBs) for lithium ion batteries.
