摘要：

Polymer electrolytes of mixtures of LiI and triblock copolymers of poly(ethylene oxide) (PEO) in combination with poly(methyl methacrylate) (PMMA) or poly (tert.-butyl methacrylate) (PTBMA) were investigated. Ac conductivity of the electrolytes and the transport number for the lithium ion were determined in dependence on salt concentration and temperature. Both systems show the same behaviour. For a composition of approximately 6 mol% LiI the investigated systems show a maximum in conductivity of 10(-4) S/cm (60-degrees-C). The transport numbers of the lithium ion are relatively small (0. 2-0.3 5) which means the iodide ion is the major ionic carrier.
