Abstract
The hydrogen-absorbing alloy electrode for alkaline storage batteries according to the invention comprises a hydrogen absorbing alloy powder prepared by grinding a strip of hydrogen absorbing alloy produced by solidifying a molten alloy by a roll method and satisfying the following relations: EQU r/t.ltoreq.0.5 (1) EQU 60.ltoreq.t.ltoreq.180 (2) EQU 30.ltoreq.r.ltoreq.90 (3) wherein r represents the mean particle size (.mu.m) of the hydrogen absorbing alloy powder and t represents the mean thickness (.mu.m) of the strip absorbing alloy. The hydrogen absorbing alloy electrode of this invention features an improved high-rate discharge characteristic at low temperature.
