Abstract: 

The influence of the way of introduction of metallic nickel as a binder into the active mass of the metal hydride electrode (MH) on the discharge characteristics of the NMH-6-type hermetically-sealed nickel-MH batteries was examined. Preliminary microcapsulating of the hydrogen-sorbing alloy by means of reduction chemical deposition of metallic nickel is shown to result in a significant increase of the discharge characteristics of the nickel-MH battery (by 45% in a whole), to enable introduction of carbonylic nickel into the active mass of the MH electrode to be completely excluded, and to raise the gas cycle efficiency in the hermetically-sealed nickel-MH battery.
