Abstract

Hybrid radical energy storage devices, such as batteries or electrochemical devices, and methods of use and making are disclosed. Also described herein are electrodes and electrolytes useful in energy storage devices, for example, radical polymer cathode materials and electrolytes for use in organic radical batteries.

First claim

We claim:

1. A method of making an electrochemical energy storage device, the method comprising:
forming a cathode using a stable polymeric organic radical-based material in a slurry cast, wherein the material and the cathode comprise at least one of

depositing the cathode on a substrate;
depositing an electrolyte on the cathode; and
depositing an anode on the electrolyte.

2. The method of claim 1 , wherein before the forming, the material is prepared by step growth polymerization.

3. The method of claim 2 , wherein the step growth polymerization is performed by at least one of anionic polymerization, rhodium catalyzed polymerization, or palladium catalyzed polymerization.

4. The method of claim 1 , wherein the electrolyte comprises at least one of a solid-state polymer, an ionic liquid, a solvent based electrolyte, or a gel.

5. The method of claim 4 , wherein the electrolyte comprises a solid-state polymer and is deposited on the cathode using a slurry printing process.

6. The method of claim 1 , further comprising drying and compressing the device, and wherein the depositing of the anode comprises adding a nanotube paper anode.

7. The method of claim 1 , wherein the anode comprises at least one of metallic magnesium or a magnesium compound.

8. The method of claim 7 , wherein the anode comprises at least one of magnesium-doped carbon or boron doped magnesium.

9. The method of claim 7 , wherein the anode further comprises at least one nanostructured carbon of single-wall nanotubes, double-wall nanotubes, multi-wall nanotubes, carbon fibers, fullerenes, graphenes, or microbeads.
