PURPOSE:To improve high rate discharge efficiency by inserting a conductive current collector inside a positive active mix. CONSTITUTION:The distances between the surface of an anode and the current collecting part of a positive case are made as uniform as possible, a current collector 9 is inserted inside a cathode active mass to prevent decrease of discharge current during discharge, and connected with a positive case 6. The current collector 9 has four pins 9a in the inside of the positive case 6 within a range below 1/2 of the inside dia, and the height of the pin is preferably 80% or less of that of the positive active mix which is placed in the positive case and pressed. |
