Patent abstract
A method for manufacturing an alkaline battery includes assembling an alkaline battery with a positive electrode, a negative electrode, a separator, and an electrolyte. The positive electrode includes cobalt and a positive electrode active material particle, which has a main component that is nickel hydroxide. The positive electrode active material particle has a coating layer that includes cobalt oxyhydroxide. At least one of the positive electrode, the negative electrode, and the electrolyte includes a tungsten element. The method further includes charging the assembled alkaline battery so that the cobalt in the positive electrode is deposited as cobalt oxyhydroxide on a surface of the positive electrode active material particle.
