Abstract

Redox flow battery performance may be improved with a metal containing ionic liquid as a liquid electrolyte. Metal containing ionic liquids are liquids at all temperatures of interest and therefore do not need dilution. As such, voltage separation between the anolyte and catholyte may exceed 0.5 V and therefor rival current state-of-the-art energy storage technologies and with higher voltage separation may attain energy densities above 100 Wh/L.
