Abstract

PURPOSE:To raise the closed circuit voltage at intermittent heavy load discharge at a low temperature during light-load discharge by adding a chloride of alkali metal to an electrolyte. CONSTITUTION:A chloride of alkali metal is added to an electrolyte. At that time it will be quite enough to add said chloride to an electrolyte in the side of a negative electrode 5. The chlorides of alkali metal are sodium chloride and potassium chloride, etc., and a potassium hydroxide solution and a sodium hydroxide solution, etc., dissolving zinc oxide are considered suitable as an alkaline electrolyte. A quantity of the additive is desirable to be in the range of 0.1-2.0mol to an alkaline hydroxide of 100ml in the electrolyte. For example, an electrolyte comprising potassium hydroxide of 35pts., zinc oxide of 5.2pts. and water of 59.8pts. in pts.wt. is prepared, and sodium chloride of 0.36pts. (1mol to 100mol of potassium hydroxide) is added for the electrolyte of 100g. The resultant is mixed to obtain a mixture comprising an amalgamated zinc and sodium polyacrylate, and is made to be a negative electrode agent 5. Hereby, since oxides on the zinc surface are dissolved, it is possible to improve intermittent heavy-load discharge characteristics during light-load discharge.
