Claims
- 1. A hydraulically and electrically rechargeable metal air battery comprising:
- a) A cell casing with a separating membrane which defines cell anode and cathode sides,
- b) A metal particle bed disposed uniformly within the anode side of the cell casing,
- c) A current collector/feeder located within the anode side,
- d) An air electrode provided within the cathode side,
- e) A current collector/feeder disposed within the cathode side,
- f) An electrolyte provided uniformly within the anode and cathode sides, and
- g) A series of flow baffles connected to the cell casing within the anode side.
- 2. The invention as recited in claim 1, additionally comprised of a flow regulator or regulators connected to said cell casing within the anode side.
- 3. The invention as recited in claim 2, wherein said flow regulator or regulators is a draft tube or tubes connected to said cell casing within the anode side.
- 4. The invention as recited in claim 1, further provided with a flow promoter connected to said anode side for circulating the electrolyte.
- 5. The invention as recited in claim 4, wherein said flow promoter is a pump connected to said anode side for circulating the electrolyte.
- 6. The invention as recited in claim 1, wherein the electroactive material of said metal particle bed is zinc or a zinc alloy.
- 7. The invention as recited in claim 1, wherein said particles are an electroactive material deposited onto the surface of electrolyte inert carrier particles.
- 8. The invention as recited in claim 7, wherein the electroactive material deposited onto the carrier particles is zinc or a zinc alloy.
- 9. The invention as recited in claim 1, wherein said air electrode is bifunctional.
- 10. The invention as recited in claim 1, wherein said air electrode is monofunctional and a third electrode is provided within the cathode side.
- 11. The invention as recited in claim 1, wherein said electrolyte is comprised of a potassium hydroxide solution.
- 12. The battery of claim 1, wherein a plurality of cells are connected in series through said current collector/feeders.
