PROBLEM TO BE SOLVED: To extend service life of forming dies of merry-go-round type when used for manufacture negative poles by adding alkaline earths titanate to the negative pole material. SOLUTION: Constituents are: a zinc positive pole material, aqueous alkaline electrolyte, separators, and negative pole material containing manganese dioxide containing 4-5weight% of electrolyte liquid added with 0.1-5weight% of alkaline earths titanate of powder state of a purity 95% or higher, grain diameter of 0.1-200 micrometers, and BET specific surface area of 0.5-500m<2> /g. This improves charging behavior of a battery and reduces gas generation in the battery. |
