%X Faced with the exhaustion of traditional energy sources, the development
of new energy devices is the current priority. Supercapacitor is a new type of energy storage device with high power density and long cycle life. Carbon material, metal oxide and conductive polymer are three common
electrode materials of supercapacitors. Based on China¡¯s energy situation, this
paper puts forward new ideas from coal to graphene to supercapacitors. In addition, the research progress of graphene
supercapacitors is summarized, including the principle of supercapacitors,
preparation methods from coal to graphene, graphene electrode materials and
different modification, and some possible scientific problems in the research
process of different modified graphene electrodes are also reviewed and
prospected.
