摘要
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 powder-like graphene active materials reported previously. The influence of the annealing temperature on the charge-discharge performance of graphene foam has been investigated.
