Abstract：Dafeng mine anthracite was used to prepare supercapacitor electrode material, low-temperature nitrogen adsorption and X-ray diffraction were applied to analyze the preparation of activated carbon under optimal conditions. The results showed that the specific capacitance in 6mol/L KOH electrolyte of activated carbon electrode material prepared under optimal conditions is 344. 976F/g. The activated carbon was in amorphous structure with reasonable pore size distribution, mainly comprised of micropores, and a certain percentage of mesopores. The electrode material has favorable capacitive performance, reversibility and cycle performance with double electrode layer energy storage, and the capacitance retention rate is over 90%.
