Polyoxometalate flow battery
Flow batteries including an electrolyte of a polyoxometalate material are disclosed herein. In a general embodiment, the flow battery includes an electrochemical cell including an anode portion, a cathode portion and a separator disposed between the anode portion and the cathode portion. Each of the anode portion and the cathode portion comprises a polyoxometalate material. The flow battery further includes an anode electrode disposed in the anode portion and a cathode electrode disposed in the cathode portion.
1. A flow battery comprising:
an electrochemical cell comprising an anode portion, a cathode portion and a separator disposed between the anode portion and the cathode portion, wherein each of the anode portion and the cathode portion comprises a same polyoxometalate material comprising a mixed addenda anion comprising vanadium and tungsten; and
an anode electrode disposed in the anode portion; and
a cathode electrode disposed in the cathode portion.
2. The flow battery of claim 1 , wherein the anode electrode and the cathode electrode are each connected to a load.
3. The flow battery of claim 1 , further comprising an anode reservoir coupled to the anode portion of the cell and a cathode reservoir coupled to the cathode portion.
4. A method comprising:
introducing a same polyoxometalate material comprising a mixed addenda anion comprising vanadium and tungsten into each of an anode portion and a cathode portion of an electrochemical cell; and
charging or discharging the cell.
