Abstract
Disclosed is a double-center bipyridyl cationic ion liquid prepared by reacting bipyridyl with haloalkane for synthesis of dialkyl bipyridyl halide, and converting the halogen ion in the dialkyl bipyridyl halide to the target anion via an ion-exchange reaction, to give the final target ionic liquid. Also disclosed are an organic electrolyte containing the double-center bipyridyl cationic ion liquid and a preparation method therefor.
