The company's product "high-performance composite three-dimensional electrode foil " using nano particles coating process to replace the traditional electrochemical etching process, breaking through the limit of specific capacitence improvement of traditional process products. At the same time, the specific capacitence of core performance is increased by more than 25%, especially suitable for the winding production of downstream aluminum electrolytic capacitors. The company's products also has obvious advantages compared with the traditional technology of leading Japanese enterprises.
