Has been done. For this reason, the negative electrode active materials for alkaline batteries that are commercially available today contain a large amount of mercury of about 5 to 10% by weight, and as a social need, the development of batteries with lower mercury or mercury-free batteries is required. It has become strongly expected.

For example, there is a zinc alloy powder in which lead is added to zinc, or a zinc alloy powder in which lead and indium are added to zinc by the present inventors (JP-A-58-181266). However, although these zinc alloy powders have some gas generation suppressing effect, they are not yet sufficient.
