Abstract

PURPOSE:To prevent any evaporation of water from an air intake, as well as any liquid leakage of a battery by using an aqueous zinc-chloride solution of high concentration as an electrolyte, providing a porous water-repellent film between the air intake and a positive black mix, and covering a negative plate with a multiple separator layer. CONSTITUTION:An intake 3 serving for taking oxygen contained in air, is provided in the bottom of a positive case 1 the inner wall of which has a corrosion- resistant conductive film 2. The bottom of the case 1 is provided with a porous water-repellent film 4, on which a positive black mix 5 is placed. A zinc plate 6 prepared by amalgamating a negative active material is made to touch a sealing plate 7, which serves for both the current collection of the negative electrode and the sealing of a battery. A multiple separator layer 8 is interposed between the positive and the negative eletrodes. The multiple layer 8 consists of starch paste which covers the negative zinc 6, and a craft paper, cellophane or the like which completely covers the outer side of the negative zinc 6. The positive black mix 5 is prepared by mixing active carbon and an aqueous zinc-chloride solution of 40- 50wt% concentration.
