Nickel hydroxide particles having an alpha - or beta -cobalt hydroxide coating layer for use in alkali batteries and a process for producing the nickel hydroxide

High-density nickel powders are produced by forming an alpha - or beta -cobalt hydroxide layer on the surfaces of and within pores of nickel hydroxide particles. The coated nickel hydroxide particles feature enhanced utilization as the positive electrode active material in alkali batteries and enabl...

Zusammenfassung:	High-density nickel powders are produced by forming an alpha - or beta -cobalt hydroxide layer on the surfaces of and within pores of nickel hydroxide particles. The coated nickel hydroxide particles feature enhanced utilization as the positive electrode active material in alkali batteries and enable the capacity of the positive electrode to be increased.
