Abstract
A zinc-alkaline battery includes a negative electrode, a positive electrode, a separator, and an electrolyte. The negative electrode contains a zinc alloy powder including 20 to 50 wt % of a micropowder with a particle size of 75 μm or less. In a constant resistance discharge, a time period for the negative electrode potential to rise is shorter than a time period for the positive electrode potential to fall.
