Investigation of the zinc electrode reaction. Annual report, October 1, 1979-September 30, 1980
The excellent performance characteristics of the nickel-zinc battery make it an attractive option for both all-battery and hydride electric vehicles. Commercialization of the battery has been delayed because of limited cycle life particularly under conditions of deep discharge. In nickel-zinc batteries, with pasted zinc electrodes, zinc electrode shape change or redistribution of the active material from the edge of the electrodes toward the center has been the major life-limiting factor. In batteries with soluble free electrolyte zinc electrodes, morphology changes, particularly under random cycling conditions, is a major operational problem. The present work was focussed on finding insights and possible solutions to these two problems. The areas covered in the work were (1) additive and substrate effects on zinc electrode morphology; (2) investigations of zinc electrodes of the second kind; (3) separator effects on zinc electrode shape change; and (4) investigation of the effect of modified charging methods on the morphology and behavior of both pasted and soluble free electrolyte zinc electrodes.
