PURPOSE:To improve the discharge characteristic by providing a hole section on the position of the air diffusion paper connected to air at the bottom section of a positive electrode case so that air can be smoothly moved into a battery. CONSTITUTION:A recess storing the air diffusion paper 1 is provided on the bottom section of a positive electrode case 2, and the diffusion paper 1 is inserted. Moisture and air are smoothly moved through the hole section 1a of the diffusion paper 1, and the discharge characteristic is improved. The movement of the moisture stuck on the inside of the bottom section of the case 2 via the air hole 9 of the positive electrode case 2 after a cell is constituted is accelerated, air is smoothly fed to the diffusion paper 1, and the stable cell discharge capacity can be secured. |
