ZINC ALLOY POWDER AND ALKALINE BATTERY WITH USAGE OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a zinc alloy powder for an alkaline battery suitable to be used for a negative electrode active material of an alkaline battery exhibiting excellent corrosion resistance and improved battery discharge characteristics, in particular high-rate discharge characteristics, and an alkaline battery with the usage of this zinc alloy powder. SOLUTION: This zinc alloy powder for the alkaline battery contains 0.001 to 0.1 wt.% of Al, 0.001 to 0.1 wt.% of Bi, and 0.001 to 0.1 wt.% of In. The zinc alloy powder for the alkaline battery contains 70 to 80 wt.% of powders having a particle size of 35 to 200 mesh, and 20 to 30 wt.% of fine powders having a particle size of -200 mesh. The zinc alloy powders are used for the negative electrode active material of the alkaline battery.
