NOVELTY - Super-critical cleaning method for deep purifying super-capacitor porous carbon material,involves using super-critical carbon dioxide cleaning depth for removing metal and non-metal impurities in porous carbon materials for energy storage of super capacitor. USE - Super-critical cleaning method for deeply purifying super-capacitance porous carbon material used in super capacitor type energy storage device such as double electric layer capacitor and battery capacitor. ADVANTAGE - The method utilizes the cleaning agent which can quickly and effectively permeate, diffuse to micropore in porous carbon material, mesoporous, thin tube, complex irregular surface, high aspect ratio structure and difficult wetting substrate and reaction with the impurity, thus removing impurity is complete; and provides super-capacitor electrode with high-purity.
