ALKALLINE STORAGE BATTERY

摘要

An alkalline storage battery (1) has an anode (2) containing beta type nickel hydroxide or/and beta type oxy nickel hydroxide as an anode active material, a cathode (3) containing a cathode active material and an alkaline solution as an electrolyte (4). The alkaline storage battery (1) is so constructed as to prevent at least part of the crystal structure of an anode active material from changing due to charging/discharging and an anode active material from exhibiting a new diffraction peak at a diffraction angle 2theta position of 8.4-10.4 deg. due to X-Ray diffraction by CuK alpha-ray. Preferably, the surface of the anode (2) may have a negative ion exchange membrane layer (25).
