Abstract
PURPOSE: To raise the liquid leaking resistance of a cell in its entirety by the addition of a process by which to remove oxide film formed on the gasket contact face of negatie current collector.
CONSTITUTION: In the negative terminal plate 6 in which the steel plate 2, etc., whose one side is provided with the nickel layer 3 and the other side is provided with the copper layer 4, is processed into a shape with the peripherally folded portion 5 by a throttling process in such a way that the copper layer 4 is turned inside, uneven oxide film is often formed on the surface of the copper layer 4 in the course of the processing, and thus the film 7 is removed at the folded portion 5 and its neighboring area as a pretreatment for the assembling of the terminal plate 6 into cell. Then, the surface 17 deprived of the film 7 is touched by the the annular gasket 16 of polyethylene, etc., and the positive electrode can 15 is clamped inwards to build up a enclosed structure inside cell. Thus, the tightness between the copper layer 4 and the gasket 16 is made better and also the creeping phenomenon of electrolyte due to the film 7 is suppressed, resulsting in the enhancement of the resistance to liquid leakage.
