Abstract

PURPOSE:To obtain a sealed alkali-manganese secondary cell with excellent pressure-proof characteristic by setting the potassium hydroxide concentration of an electrolyte to the wt.% within the specific range. CONSTITUTION:This secondary cell has a positive electrode case 1, a positive electrode 2 arranged in the case 1 and mainly made of manganese dioxide, a positive electrode ring 3 arranged on the upper outer periphery of the positive electrode 2, a separator 4 arranged on it and made of polyethylene graft polymerized film, and a negative electrode 6 arranged on it via an impregnator 5. A sealing plate 7 covering this negative electrode 6 and concurrently serving as a negative electrode terminal and an insulating sealing ring 8 inserted between the plate 7 and the positive electrode case 2 are also provided. An electrolyte solved with zinc oxide and having the potassium hydroxide concentration within a range of 38-50wt.% is used as the electrolyte impregnated in the positive electrode 2, negative electrode 6, and impregnator 5.
