| Abstract: | A redox flow battery is described herein that has a
sodium-super-ionic-conductor NaSICON barrier disposed between an anolyte
chamber of the battery and the catholyte chamber of the battery. The
NaSICON barrier prevents crossover of solvents or active redox species
between the anolyte chamber and the catholyte chamber, while permitting
transport of sodium ions between the chambers. In exemplary embodiments,
the anolyte chamber includes an anolyte solution that comprises a first
active redox species dissolved in a first solvent, while the catholyte
chamber includes a catholyte solution that comprises a second active
redox species dissolved in a second solvent. |
