Abstract
An alkaline storage battery in which an actual reaction area is not reduced after increasing a reaction area is provided. A hydrogen storage alloy negative electrodeof an alkaline storage batteryof the present invention is formed in a strip form including a long axis and a short axis, in which the ratio (A/B) of a length A (cm) of the long axis to a length B (cm) of the short axis is 20 or more and 30 or less (20≦A/B≦30), and the ratio (X/Y) of an electrolyte volume X (g) retained in the hydrogen storage alloy negative electrodeto an electrolyte volume Y (g) retained in a separatoris 0.8 or more and 1.1 or less (0.8≦X/Y≦1.1). With this arrangement, an alkaline storage battery with high output characteristics and long-term durability performance is obtained.
