Ionic transport measurements of LiCF3SO3 doped polyimide-diaminobenzenesulfonic acid copolymer

In an effort to develop polymer electrolytes suitable for high temperature electrochemical operation, a polymer electrolyte based on the lithium salt doped copolymer of 1, 2, 4, 5-benzenetetracarboxylic dianhydrite (PMDA), 4-aminophenyl ether (ODA), 2, 5-diaminobenzene sulfonic acid (DABSA) has been prepared. As LiCF3SO3 showed the best conductivity results within the lithium compounds, it was selected as our primary dopant. Infrared …
