摘要

<span style="font-family:Verdana;">Faced with the exhaustion of traditional energy sources, the development of new energy devices is the current priority. </span><span style="font-family:Verdana;">Supercapacitor</span><span style="font-family:Verdana;"> is a new type of energy storage device with </span><span style="font-family:Verdana;">high</span><span style="font-family:Verdana;"> power density and long cycle life. Carbon material, metal oxide </span><span style="font-family:Verdana;">and</span><span style="font-family:Verdana;"> 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. </span><span style="font-family:Verdana;">In addition</span><span style="font-family:Verdana;">, 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.</span>
