PURPOSE:To improve the anticorrosive property of a zinc negative electrode while reducing the gelatinization rate to realize a low public hazard by using a specific polyoxyechylene alkylether as the anticorrosive of a negative electrode active substance. CONSTITUTION:In a positive electrode can 1, a positive electrode compound 5 mainly of manganese dioxide, a separator 6, and a zinc negative electrode 7 are provided. And at the opening of the positive electrode can 1, a negative electrode terminal plate 2 is installed through a sealing gasket 3, and the negative electrode terminal plate 2 is connected electrically with the zinc negative electrode 7 through a collector rod 4. And as an anticorrosive of the negative electrode active substance, polyoxyethylene alkylether shown as the formula I (omitted in the figure) is used. (In the formula I, R is an alkil radical, and n is the polymerization rate of the polyoxyethylene). Consequently, the anticorrosive property of the zinc negative electrode can be improved while the gelatinization rate is reduced to realize a low public hazard. |
