This study was performed to explore the feasibility of using a supported liquid membrane (SLM) as a separator in the nickel-zinc battery. In particular, SLM separators should prevent zinc dendrite growth from shorting out the cell and might also alleviate capacity loss due to zinc electrode shape changes. A number of ion exchange/solvent modifier systems for incorporation into SLMs were developed under a previous LBL contract. SLMs prepared with these reagents exhibited resistances in the range of 0.4 to 10 ohm cm/sup 2/, selectively transported hydroxyl ions over zincate ions by a factor of 10/sup 6/ to 10/sup 7/, and possessed eletrochemical and chemical stability in alkaline electrolytes. In order to evaluate these SLM separators under conditions closely resembling a commercial Ni-Zn cell, an accelerated cycle life test was devised using commercial electrodes.
