Abstract
A nickel-hydrogen secondary battery comprising, a positive electrode containing nickel hydroxide, a negative electrode containing a hydrogen-absorbing alloy, a separator interposed between the positive electrode and the negative electrode and containing olefin-containing-polymer based fibers having an ion-exchange group, and an alkaline electrolyte having a normality of 5 or more in concentration, wherein the separator satisfies the following equation (1): EQU {0.409-(X/55)}.ltoreq.Y.ltoreq.{0.636+(2X/55)} (1) PA1 where X is a chemical equivalent of alkaline electrolyte per 1 Ah of battery capacity (meq/Ah) and Y is an ion-exchange capacity of the separator per 1 Ah of battery capacity (meq/Ah).
