Carbon-coated oxidized graphite has been prepared by a liquid-state deposition method. Oxidized graphite wasprepared by wet chemical oxidation. Oxidation increases the reversible capacity of graphite
but its initial charge anddischarge efficiency was reduced. Phenolic resin was applied to form the disordered carbon layer on the oxidized graphite.The efficiency and reversible charge capacity were obviously increased. The morphology of carbon materials wasinvestigated by SEM.
