Abstract

PURPOSE:To facilitate the absorption of oxygen gas generated during over discharge or charging of a battery, by using a gel-like zinc negative electrode an air-room side end of which contains a higher concentration of dispersed amalgamated zinc powder than the inner part of that. CONSTITUTION:A positive electrode 2 made manganese dioxide, and a gel-like negative electrode 3 containing zinc are placed opposite to one another, with a separator 4 interposed between them. The concentration of an amalgamated zinc powder dispersed in the gel-like electrolyte of an end part 3', which is a part of the negative electrode 3 and touches an air room 6, is made higher than that of the amalgamated zinc powder dispersed in the electrolyte of the inner part of the electrode 3. The electric capacity of the end part 3' containing a higher concentration of dispersed amalagamated zinc powder is preferably 10-20% of the capacity of a positive electrode. The electric capacity of the negative electrode is preferably 100-120% of the capacity of the positive electrode. Owing to the above constitution, oxygen gas, which is generated from the positive electrode either when reversal is developed due to over discharge or when charging is carried out, can be easily absorbed. Consequently, any rise of the internal gas pressure of a battery can be prevented, and the explosion as well as the breakdown of the battery can be obviated.
