PURPOSE:To allow a pneumatic button battery to be used both for strong electrodischarge and weak discharge by furnishing two types of air dispersion paper with different amounts of air penetration, and placing one of the dispersion papers on one air hole while the other dispersion paper on the other air hole. CONSTITUTION:The bottom surface of a positive electrode case 1 is equipped with a recess 10 having two air holes 2-a, 2-b. An air dispersion paper 3-L with an amount of air penetration ranging 6000-8000sec expressed by Gahre number is placed on one of these air holes 2-a, while another air dispersion paper 3-s having an amount of air penetration ranging 12000-14000sec by Gahre number placed on the other air hole 2-b. This enables manufacture divided for the purpose according to the battery designed for strong discharging or weak discharging, and unevenness in the discharging performance will be suppressed to result in stabilization. |
