Synthesis and characterization of aluminate polymer electrolytes and their blends with poly(ether)s

A series of single ion conducting aluminate polymer electrolytes were synthesized and their blends with poly(ether)s characterized. A great improvement of mechanical properties and processability was obtained upon blending with poly(ethylene oxide) or an ethylene oxide–propylene oxide copolymer. Enhancement of the ionic conductivity of blended polymer electrolytes was observed by adding LiCF3SO3 and cationic transference numbers were determined to be about 0.56.
