Nickel-metal hydride high-capacity cylindrical battery

The utility model belongs to the technical field of nickel-metal hydride batteries, and provides a nickel-metal hydride high-capacity cylindrical battery, comprising a shell, and an anode piece, a cathode piece, a diaphragm and electrolyte which are arranged in the shell, wherein one tail end of the anode piece takes the shape of a wedge with an inclined surface. According to the nickel-metal hydride battery, as the shape of the tail end of the anode has certain inclination, when in winding, the wedge-shaped surface faces downwards, so as to just fill an empty space at the tail end, thus improving the space utilization rate; and simultaneously, a battery cell has better degree of circularity, the steel shell has less deformation after entering the shell, and subsequent working procedures of slotting and sealing have higher finished product ratio.
