Abstract
The present invention relates to a steel strip basal body hydrogen-nickel rechargeable button cell, which comprises a positive plate provided with a nickel electrode, a negative plate composed of complex multiphase electrochemical hydrogen storage alloy powders, a diaphragm arranged between the positive plate and the negative plate, a cell shell to hold an assembly of all components above with a gasket ring and a cell cover, a meshed gasket arranged between an internal bottom of the cell shell and the positive plate, a meshed gasket and a spring cushion positioned between the negative plate and the cell cover. The present invention eliminates a problem that powder easily falls off for negative hydrogen electrodes with steel strips as basal bodies, thus enhancing performance of heavy current charge and discharge, reducing cost and saving resource.
Description
technical field [0001] The invention belongs to the technical field of batteries, and in particular relates to a nickel-hydrogen button-type rechargeable battery with a steel strip matrix. Background technique [0002] Because the hydrogen negative electrode with the steel strip as the substrate is easy to lose powder during the charging and discharging process, it is only used in the nickel-cadmium button rechargeable battery at present, and has not been used in the manufacture of the nickel-hydrogen button battery. At present, the nickel-hydrogen button rechargeable battery mainly uses nickel foam as the substrate, and the assembly method is formed by vertically stacking the positive plate, the diaphragm, and the negative plate. Its disadvantages are high cost, and the nickel foam matrix is easy to break, the battery reliability is poor, the plate is deformed and the recovery is poor when charging with high current, its charge and discharge cycle life is short, and it is...
