Summary: | PURPOSE:To reduce production cost of current collector of alkaline battery and decrease the progress of alkaline electrolyte creepage caused by amalgamation by forming a slender iron rod in a desired shape, applying Fe-Zn alloy plating on the iron rod, and using it as a negative current collector. CONSTITUTION:A positive mix 2 comprising the mixture of positive active material, conductive material, and electrolyte is pressed against the inside of a positive can 1 comprising nickel plated iron plate. A gelled negative electrode 4 mainly comprising amalgamated zinc powder is accommodated into the hollow part of the positive mix 2 through a separator. A slender iron rod is formed so as to have a head 5a having larger diameter, a pip 5c, and a tapered edge 5b by a mold, then Fe-Zn alloy plating is applied on its surface to form a negative current collector 5. One end of the current collector is welded to a negative terminal plate 8, and the other end is inserted into the boss of a sealing gasket 6. The current collector is inserted into the gelled negative electrode 4, then a battery is assembled. The Fe-Zn alloy plating prevents the iron base material from rusting. |
