NICKEL ACTIVE SUBSTANCE FOR ALKALINE BATTERY AND MANUFACTURE THEREOF

摘要

PURPOSE: To provide nickel active substance for an alkaline battery and manufacturing method thereof which can enhance electrode capacity by allowing cobalt compound to sufficiently exhibit its function in a nickel hydroxide active material with which the cobalt compound is compounded. CONSTITUTION: A nickel active substance for an alkaline battery is such one in which a part or the whole of the surfaces of basic particles including nickel hydroxide as its main component is covered with metallic compound including at least cobalt hydroxide. This nickel active substance has its average particle diameter caused by laser diffraction method set to 3μm or more and less than 20μm.
