A symmetric composite electrode porose current collector double membrane safety valve coiled storage battery comprises a battery shell and a battery cell. The symmetric composite electrode porose current collector double membrane safety valve coiled storage battery is characterized in that the battery cell comprises a positive plate, a negative plate and a diaphragm located between the positive plate and the negative plate, the positive plate, the negative plate and the diaphragm are coiled to form a column through a battery cell winding shaft, and a positive current collector and a negative current collector are arranged on the end roofs of the two ends of the battery cell; an electrode lug with the length equal to that of the positive plate is arranged at the top end of the side, close to the positive current collector, of the positive plate, the electrode lug is a positive continuous electrode lug, the positive plate and the negative plate are composite electrodes, and the construction of the positive plate and the negative plate is that a lead plate serves as a bottom plate which is provided with metal oxide coatings distributed in a striped mode. The symmetric composite electrode porose current collector double membrane safety valve coiled storage battery has the advantages that the current conducting capacity is effectively improved through the unique end surface current collection structure and the composite electrodes; meanwhile, the battery has super-capacitor high-rate charging and discharging characteristics, a double membrane safety valve can better protect the battery, and the battery user performance is improved.
