Electrochemical Properties of Graphene Paper Electrodes Used in Lithium Batteries.

Chemically prepared graphene was used to form highly active electrodes for use as a cathode in a Li battery. The first discharge process gave a flat discharge plateau at 2.20 V at a current density of 50 mA g−1, and a discharge capacity of 528 mA h g−1was obtained with a cutoff voltage of 2.0 V.
