ALKALI BATTERY AND METHOD FOR MANUFACTURING POSITIVE ELECTRODE MATERIAL FOR ALKALI BATTERY

摘要

An alkali battery is provided with a positive electrode containing a positive electrode material containing nickel hydroxide, a cobalt-cerium compound containing cobalt and cerium, and a compound with at least one element among calcium, yttrium, europium, holmium, erbium, thulium, ytterbium and lutetium. Furthermore, the positive electrode material is manufactured by mixing powders of nickel hydroxide particles, a cobalt-cerium compound, and a compound with at least one element among calcium, yttrium, europium, holmium, erbium, thulium, ytterbium and lutetium
