Claims12
A redox flow battery comprising:
- a cathode;
- a catholyte comprising a transition metal ion and a first supporting electrolyte wherein the transition metal ion and the first supporting electrolyte form a first solvation structure having a diameter in a range of from about 0.1 nm to about 3 nm;
- an anode;
- an anolyte comprising a lanthanide ion and a second supporting electrolyte, wherein the lanthanide ion and the second supporting electrolyte form a second solvation structure having a diameter in a range of from about 0.1 nm to about 3 nm;
- and
- a permselective ion exchange membrane separating the cathode and the catholyte from the anode and the anolyte.
