With the rapid development of modern society, the energy and environmental issues have become increasingly prominent. Supercapacitors have attracted much attention because of their high power density, high energy density and long service life. The electrode material and structure determine the performance of the supercapacitor. Therefore, the development and optimization of the electrode material preparation process has become the top priority of research. The research status and development trend of supercapacitor electrode materials prepared by laser fine processing are introduced.
