Title:
NEGATIVE ELECTRODE ZINC GROUP ALLOY FINE PARTICLE FOR ALKALINE BATTERY, AND ALKALINE BATTERY USING THIS FINE PARTICLE
Document Type and Number:
Japanese Patent JP2002025552
Kind Code:
A
Abstract:

To improve discharging characteristics while suppressing the amount of generated gas, and to raise yield of zinc group alloy fine particles when producing them using equipment for atomizing or the like, in the zinc group alloy fine particles for a negative electrode of an alkaline battery.

The zinc group alloy fine particles are produced by adding to zinc 0.001 to 0.5 weight % of bismuth, 0.001 to 0.5 weight of tin, 0.001 to 0.3 weight % of titanium, and 0.001 to 0.5 weight % of aluminum. Moreover, the zinc group alloy fine particle are produced by adding to zinc 0.001 to 0.5 weight % of bismuth, 0.001 to 0.5 weight of tin, 0.001 to 0.5 weight % of zirconium, and 0.001 to 0.5 weight % of aluminum.
