Progress in sealed Ni-Zn cells, 1991–1995

Novelties in the development of sealed nickel-zinc cells are reviewed. The zinc electrodes remain the problem-limiting factors for long-operating cells and batteries. A tendency to light and inexpensive non-sintered nickel porous supports based on fibres at the positive electrodes in the Ni-Zn system is presented. Sealed Ni-Zn cells are discussed. The activity of the Far East Asian countries in this field is increasing continuously.
