Abstract
Disclosed is an alkaline storage battery comprising a negative electrode, a positive electrode, a separator and an alkaline electrolyte solution in a package can. The negative electrode contains a hydrogen storage alloy represented by the following general formula: LnMg(NiT)(wherein Ln represents at least one element selected from lanthanoid elements, Ca, Sr, Sc, Y, Ti, Zr and Hf; T represents at least one element selected from V, Nb, Ta, Cr, Mo, Mn, Fe, Co, Al, Ga, Zn, Sn, In, Cu, Si, P and B; and 0<x≦1, 0≦y≦0.5 and 2.5≦z≦4.5) as a negative electrode active material. In this alkaline storage battery, the hydrogen equilibrium pressure (P) is regulated to satisfy 0.02 MPa≦P≦0.11 MPa when the hydrogen amount stored in the hydrogen storage alloy (H/M (atomic ratio)) at 40° C. is 0.5.
