Abstract: A redox flow battery is described that does not include ion-exchange resin such as an expensive proton exchange membrane but rather uses immiscible catholyte and anolyte liquids in contact at a liquid-liquid interface. Solvents and electrochemically active components of the anolyte and catholyte would not cross the liquid-liquid interface between the anolyte and catholyte, but certain ions in each of the anolyte and catholyte would cross the interface during charging and discharging of the redox flow battery. Suitable chemical options are described along with system options for utilizing immiscible phases.

Abstract: A redox flow battery is described that does not include an ion-selective resin such as a proton exchange membrane but rather uses a generally stationary separator liquid that separates the anolyte from the catholyte at immiscible liquid-liquid interfaces. Solvents and electrochemically active components of the anolyte and catholyte would not cross the liquid-liquid interfaces between the separator liquid and the anolyte and catholyte, but certain ions in each of the anolyte and catholyte would cross the interface during charging and discharging of the redox flow battery. The separator liquid comprises a relatively small total volume of liquid in such a flow battery arrangement as compared to the anolyte and catholyte. Suitable chemical options are described along with system options for utilizing immiscible phases.

Abstract: Redox flow battery efficiency and performance may be improved with a high energy density bipyridinium based ionic room-temperature liquid electrolyte. Current electrolytes require solvent to dissolve the redox-active material and a supporting electrolyte to maintain charge balance. A room temperature redox-active electrolyte having intrinsic charge balancing would not need a solvent to form a liquid and would therefore have a higher density of anions and cations involved with charge storage. As such, creating redox-active bipyridinium core ionic materials that are in a liquid form at room temperature or, more particularly, are liquids across the range at which a redox flow battery would operate permit smaller and less costly flow battery design than conventional flow batteries.
