Nickel Sekundärbatterie und Verfahren zu deren Herstellung

摘要

A nickel-series rechargeable battery whose cathode active material comprising a material containing an amorphous phase-bearing nickel hydroxide particulate which in X-ray diffraction using K alpha -rays of Cu as a radiation source, has a diffraction peak of a (001) face appeared near a diffraction angle 2&thetas; = 19 DEG having a half-value width of more than 1.2 DEG and has a diffraction peak of a (101) face appeared near a diffraction angle 2&thetas; = 38 DEG having a half-value width of more than 1.5 DEG . A process for the production of said rechargeable battery.
