Polymer-graphene nanocomposites as high-rate “green” electrodes for Li-ion batteries

Green Car Congress

A team of researchers from the US and China have developed novel polymer?graphene polymer with a stable skeleton and highly electroactive functional group can potentially be a high-power cathode candidate because its redox reaction intrinsically has faster kinetics than inorganic intercalation cathodes.
