Asymmetric ultracapacitor system of high -energy -density and high power density

The utility model provides an asymmetric ultracapacitor system of high -energy -density and high power density, includes anodal shell, the anodal mass flow body, anodal active layer, diaphragm, negative pole active layer, negative current collector, negative pole lid and sealing washer. Separate with the diaphragm between anodal active layer and the negative pole active layer. The condenser positive pole comprises the anodal mass flow body and anodal active layer, the condenser negative pole comprises negative current collector and negative pole active layer. Condenser positive pole, negative pole and diaphragm are all fully soaked by electrolyte. Anodal active layer use alpha - mnO2 is electric active material, negative pole active layer use mesopore active carbon is electric active material. The advantage is: the electrochemical activity current potential window of alpha - mnO2 and mesopore active carbon fully staggers, has increased substantially the operating voltage of condenser to improved the specific energy, simultaneously, two kinds of active material all have fine power characteristic, make asymmetric condenser has high power density.
