This project has developed the concept of using a supported liquid              membrane (SLM) in an electrochemical cell.  A supported liquid membrane         consists of an organic ion complexing agent and a suitable modifier,            forming a solution substantially insoluble in aqueous electrolyte,              infused into a hydrophobic microporous polymer support and held in by           strong surface tension forces.  The ability to provide specific ion             transport and low resistivity at high current densities makes the SLM a         candidate for a new generation of superior electrochemical separators           with a wide variety of industrial applications in electrowinning of             metals, electrosynthesis, and the generation and storage of                     electrochemcial energy.  This effort combines further development of            SLMs as separators with a strong research effort directed at better             understanding the mechanism of electrotransport in SLMs and the factors         necessary to provide high specific ionic conductivity to liquid organic         phase.  This new understanding will aid in choosing SLM compositions            suitable for direct electrowinning of pure nickel and cobalt from               solutions containing both ions.
