DETAILED DESCRIPTION - Preparing graphene lithium composite electrode material involves premixing quinone compound, and deionized water at room temperature, and stirring until raw material is completely dissolving to obtain mixture. The graphene oxide is dissolved de-ionized water, mixed, and stirred at normal temperature until raw materials are completely dissolved. The liquid conductive polymer is added to mixed solution, and stirred at normal temperature. The dried stainless steel mesh as substrate is immersed in mixed solution. The graphene and conductive polymer is oxidized through quinone compound in constant current solution under excitation of current and eventually deposited together to obtain black mesh electrode on stainless steel wire. The black mesh electrode is placed into reductant solution and placed in oven for 30-180 minutes, placed at room temperature for 12-48 hours to obtain composite electrode material.
