Abstract   For the defect that the mechanical properties of polypyrrole supercapacitors decrease with charge and discharge cycles, and the cycle stability is poor, a compound method of polypyrrole electrode for supercapacitors based on multi-walled carbon nanotubes is proposed. The structure of the formed polypyrrole coated multi-walled carbon nanotubes effectively increase the specific surface area of the electrode material, the utilization rate of the active material and the electrical conductivity, improve the rapid charge and discharge performance of the electrode material, and greatly improve cyclic stability of polypyrrole. The composite electrode materi- al of polypyrrole and functionalized multi-walled carbon nanotubes for supercapacitors is prepared by pulse current deposition meth- od. It is scanned at a scanning rate of 1000mV?s -1 in a 3mol?L -1 potassium chloride electrolyte, after 100,000-cycle, the capacity on- ly declines by 16%.
