Pemsler, J P; Dempsey, M D

In this one year effort of research into supported-liquid-membrane (SLM) separators for the zinc-ferricyanide battery systems, at least one SLM separator (80% LT27/M80 on 0.13 mm PTFE), has been found that approaches the required specifications with separator resistance in the 2 to 3 ohm-cm/sup 2/ range, 1 x 10/sup -3/ mmoles Fe/h-cm/sup 2/ iron transport and 2 x 10/sup -4/ mmoles Zn/h-cm/sup 2/ zinc transport. This separator is still being tested in a 60-cm/sup 2/ zinc-ferricyanide battery and is exhibiting encouraging results.
