Abstract
The electrode membrane of the invention has high ion-selectivity for lithium ions relative to other alkali and alkaline earth metal ions. The membrane is shaped from a polymeric composition comprising a polymeric material, e.g., a polyvinyl chloride resin and poly(1,2-butadiene), a plasticizer and, as the ion carrier, a derivative of 1,10-phenanthroline such as 2,9-dimethyl-1,10-phenanthroline and 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline.
