Taking high-quality Taixi coal of Shenhua Ningxia Coal Group as raw material, the coal-based activated carbon(AC) for super capacitor was prepared by activation treatment at 800 ~ 850 ℃ with the physical-chemical process. And the pore size and morphology of activated carbon before and after the modification were characterized. Characteristics and specific capacitance of the capacitor prepared by using above activated carbon as the super capacitor electrode were studied with the testing methods of cyclic voltammetry and constant current charging-discharging. The results show that the activated carbon super capacitor electrode prepared from high-quality Taixi coal has better chemical corrosion resistance, smaller thermal expansion coefficient, lower density and better thermal conductivity and higher current electrical conductivity.
