They are widely used in power system stability control, intelligent robots, wearable devices, energy-saving lamps and other fields. Among them, electrode materials are the key to the performance of supercapacitors. Therefore, this paper focuses on the preparation and application of high-performance supercapacitor electrode materials.In terms of preparation, this paper mainly introduces the preparation methods and advantages and disadvantages of electrode materials such as active materials, nano materials, and two-dimensional materials, and discusses the application of auxiliary preparation technologies such as additives and template methods. In terms of application, this paper mainly introduces the application of supercapacitors in energy storage, sensing, circuit modeling, etc.Through a literature review and analysis, it is found that active materials, nano materials, and two-dimensional materials all have excellent capacitance performance, but there are certain limitations in terms of stability and cost. Therefore, in the future, it is necessary to further develop sustainable and low-cost electrode materials, such as the reuse of biomass materials and waste materials.Keywords: supercapacitor; electrode material; active material; nano material; two-dimensional material.
