Abstract
The hybrid air-slurry flow cell battery is at least one flow cell having a core area having an anode, a cathode parallel to the anode, and an ion-selective membrane disposed between the anode and the cathode to define parallel anolyte and catholyte flow paths through the core area on opposite sides of the membrane. An electrolyte tank is connected to the input and output of one of the flow paths to circulate a slurry containing a first electrochemically active redox reactant adsorbed on carbon particles suspended in a solvent between the electrolyte tank and the flow path through the core area. A gas diffusion electrode is connected to the other flow path, the gas (preferably air or oxygen) including a second electrochemically active redox reactant forming a redox couple with the first. A redox reaction across the membrane generates a voltage differential between the electrodes.
