Li+ Transference Number Enhancement in Polymer Electrolytes by Incorporation of Anion Trapping Boroxine Rings into the Polymer Host

Abstract Polymer electrolytes incorporating boroxine rings with pendant oligoether side chains and a variety of dissolved lithium salts were prepared. High ionic conductivities and Li+ transference numbers were observed, the latter being ascribed to the anion trapping ability of the boroxine ring.
