Abstract

PURPOSE:To sharply shorten the time until the open circuit voltage of a cell reaches the preset value by arranging an air diffusion paper processed in a wave shape centering an air hole at the bottom inside the bottom of a bottomed cylindrical positive electrode case. CONSTITUTION:An air diffusion paper 6 is arranged centering a bottom air hole 8 inside the bottom of a bottomed cylindrical positive electrode case 7. The air diffusion paper 6 is molded with multiple wave-forms with the height of 0.3mm, the oxygen flowing in through the bottom air hole 8 is made easier to diffuse to the outer periphery. The time until the open circuit voltage of a cell reaches the fixed level after a seal plate 9 is removed from the bottom air hole 8 of the positive electrode case 7 can be sharply shortened.

Description

【発明の詳細な説明】 産業上の利用分野 本発明は、空気ボタン電池の、開路電圧特性の改良に関

空気極中に存在する酸素との間で電位が生じ、電池とし
て開路電圧が発生する。Conventional air button batteries use oxygen as the positive electrode active material, and when the battery is used, the sealing material is peeled off from the bottom of the positive electrode case. By doing so, 6 oxygen in the atmosphere reaches the air electrode via the air hole air diffusion paper water-repellent membrane, and at that point, a potential is generated between the negative electrode active material and the oxygen present in the air electrode, and the battery An open circuit voltage is generated as a result.

がその際に空気拡散紙中央部（空気孔が存在する箇所）
より外周部方向に放射線状で拡散する。よって空気拡散
紙中央部では、酸素は撥水膜へ到達し易いが、空気拡散

点から電池の開路電圧が、器具使用に必要な一定のレベ
ルに達する迄に、約６０秒前後の時間を必要とした。Problems to be solved by the two-cage invention Oxygen that flows in through the air holes diffuses inside the air diffusion paper, but at this time, the central part of the air diffusion paper (where the air holes are present)
It spreads more radially toward the outer periphery. Therefore, in the center of the air diffusion paper, oxygen can easily reach the water-repellent film, but near the outer periphery of the air diffusion paper, the rate of oxygen diffusion is slower than in the center. It took about 60 seconds for the open circuit voltage of the battery to reach a certain level necessary for use of the device.
