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.

Claims19

Dependent claims

A redox flow battery comprising:

a catholyte;
an anolyte;
a catholyte storage tank for storing the catholyte;
an anolyte storage tank for storing the anolyte;
a power cell arranged for catholyte and anolyte to coexist and be physically separated while also in ion communication with one another;
a catholyte pump to circulate the catholyte from the catholyte storage tank to the power cell and back to the catholyte storage tank;
and
an anolyte pump to circulate anolyte from the anolyte storage tank to the power cell and back to the anolyte storage tank;
wherein one of the catholyte and anolyte comprises a metal-containing ionic liquid.
