Claims
- 1. A battery element useful as a recombinant separator in a valve regulated lead acid battery having active material and sulfuric acid electrolyte comprising a recombinant separator and an additive amount of a plurality of acid resistant three dimensional elongated fresh water inorganic diatomite macroporous particles having at least a part hydrophobic surface properties to improve participation of the electrolyte contained in the separator during repetitive discharge and charge cycles of the battery provided that said macroporous particles are associated with said recombinant separator and in contact with the electrolyte to allow said electrolyte to substantially permeate the internal surfaces of the macroporous polymers.
- 2. The element of claim 1 wherein the porous particles have a fiber-like geometry.
- 3. The element of claim 1 wherein the mean macropore diameter is from about 0.075 to about 10 microns.
- 4. The element of claim 1 wherein the part hydrophobic surface is from surface treatment with a silica based size.
- 5. The element of claim 2 wherein the part hydrophobic surface is from surface treatment with a silica based size.
- 6. The element of claim 3 wherein the porous particles have a mean pore diameter of from about 0.1 to about 5 microns.
- 7. A battery element useful as a recombinant separator in a valve regulated lead acid battery having active material and sulfuric acid electrolyte comprising a recombinant separator and an additive amount of a plurality of acid resistant three dimensional elongated organic macroporous particles having at least a part hydrophobic surface properties to improve participation of the electrolyte contained in the separator during repetitive discharge and charge cycles of the battery provided that said macroporous particles are associated with said recombinant separator and in contact with the electrolyte to allow said electrolyte to substantially permeate the internal surfaces of the macroporous polymers.
- 8. The element of claim 7 wherein the particles are selected from the group consisting of a polyolefin, a poly-vinyl polymer, a phenol formaldehyde polymer, a polyester polymer, a polyvinylester polymer and mixtures thereof.
- 9. The element of claim 7 wherein the porous particles are polyolefin and the polyolefin is polypropylene.

- 11. The element of claim 9 wherein the mean macropore diameter is from about 0.075 to about 10 microns.
- 12. The element of claim 7 wherein the macroporous particles have at least part hydrophobic and hydrophillic surfaces.
- 13. A battery element useful as a recombinant separator in a valve regulated lead acid battery having active material and sulfuric acid electrolyte comprising a recombinant separator and an additive amount of a plurality of acid resistant three dimensional elongated resilient organic macroporous particles having at least a part hydrophobic surface properties to improve participation of the electrolyte contained in the separator during repetitive discharge and charge cycles of the battery provided that said macroporous particles are associated with said recombinant separator and in contact with the electrolyte to allow said electrolyte to substantially permeate the internal surfaces of the macroporous polymers.
- 14. The element of claim 13 wherein the particles are selected from the group consisting of a polyolefin, a poly-vinyl polymer, a phenol formaldehyde polymer, a polyester polymer, a polyvinylester polymer and mixtures thereof.
- 15. The element of claim 14 wherein the porous particles are polyolefin and the polyolefin is polypropylene.
- 16. The element of claim 13 wherein the mean macropore diameter is from about 0.075 to about 10 microns.
