Abstract

A road embedded battery includes a first encapsulation layer disposed on top of a road grade base. A first conductor mesh is disposed on top of the first encapsulation layer and an anode material is embedded into to first conductor mesh. A permeable membrane is disposed on top of the anode material. A second conductor mesh is disposed on top of the permeable membrane and a cathode material is embedded into the second conductor mesh. A second encapsulation layer is disposed on top of the cathode material.

First claim

What is claimed is:

1. A road embedded battery, comprising:
a plurality of cathodes, wherein the cathodes are formed from vertically-oriented metal current collectors coated with one or more active cathode materials;
a plurality of anodes, wherein the anodes are formed from vertically-oriented metal current collectors coated with one or more active anode materials;
an electrolyte between the plurality of cathodes and plurality of anodes;
wherein the plurality of cathodes, the plurality of anodes, and electrolytes are disposed, at least partially, under a roadway;
wherein the road embedded battery is connected to the electrical grid and configured to be charged by power from the electrical grid and to reinject power to the electrical grid; and
wherein the vertically-oriented oriented metal current collectors include sheet pile.

2. The road embedded battery of claim 1 , wherein in the active cathode materials includes a lead oxide coating, the active anode material includes lead, and the electrolyte includes aqueous sulfuric acid.

3. The road embedded battery of claim 1 , wherein in the active cathode materials includes carbon felt or cloth, the active anode material includes zinc.

4. The road embedded battery of claim 1 , wherein the active cathode materials include one or more of materials selected from the group consisting of:
Mn-based oxides, Mn-based phosphates, Mn-based silicates, V-based phosphates, V-based silicates, metal hexacyanoferrates, and activated carbon; and wherein the active anode materials include one or more of materials selected from the group consisting of:
sodiated metal oxides, sodiated metal sulfides, and metal phosphates.

5. The road embedded battery of claim 1 , wherein the electrolyte includes one or more aqueous solutions selected from the group consisting of: NaCl, Na2SO4, CH3COONa, NaNO3, ZnCl2, ZnSO4, Zn(CH3COO)2, Zn(NO3)2, NiCl2, NiSO4, Ni(CH3COO)2, Ni(NO3)2, MnCl2, MnSO4, Mn(CH3COO)2, and Mn(NO3)2.

6. The road embedded battery of claim 1 , wherein the vertically-oriented metal current collectors include corrugated metal.
