Organic Electrolyte Permselective Membranes.
Abstract
This investigation is concerned with the evaluation of membrane separators for prevention of self discharge in the lithium-copper chloride-propylene carbonate (PC) cell. Measurements of electrical conductance were completed for six commercial and specially prepared cation exchange membranes in half-molar lithium perchlorate-PC at 25C. In order to combine the advantages of cation selectivity and low resistance, laminated membranes consisting of a thin layer of phenolsulfonic acid-formaldehyde cation exchange resin on a polypropylene support were prepared. They were found to be chemically stable in PC with moderate electrical resistance. A commercial laminar membrane was also tested and found to be stable. The rate of diffusion of cupric perchlorate through the membrane into pure PC was found. (Author)
