In order to increase the current efficiency during high rate discharge, the internal resistance of the battery is extremely reduced, and the voltage drop during high rate discharge is minimized. Among the connecting conductive plates, the one for the cathode has a protrusion welded to the peripheral edge of the electrode plate and a can contactor welded to the can which also serves as a cathode terminal.
