The present invention is directed to liquid monomer mixtures that comprise at least one metal salt, at least one ionic liquid, at least one monomer, and at least one polymer initiator. The present invention is also directed to methods of making gel polymer electrolytes from the liquid monomer mixtures and methods of using the gel polymer electrolytes in batteries and other electrochemical technologies.

Carbon fiber battery electrodes with ionic liquid and gel electrolytes

Described are structural electrode and structural batteries having high energy storage and high strength characteristics and methods of making the structural electrodes and structural batteries. The structural batteries provided can include a liquid electrolyte and carbon fiber-reinforced polymer electrodes comprising metallic tabs. The structural electrodes and structural batteries provided can be molded into a shape of a function component of a device such as ground vehicle or an aerial vehicle.

Structural lithium-ion batteries with carbon fiber electrodes

A sodium ion battery comprises a cathode having a porous redox active metal-organic framework material. The battery can be an organic electrolyte sodium ion battery wherein the electrolyte comprises a sodium salt dissolved in an organic solvent or mixture of organic solvents. Alternatively, the battery can comprise an aqueous sodium ion battery wherein the electrolyte comprises a sodium salt dissolved in an aqueous solvent. Battery performance is especially related to electrolyte and binder selection.

Metal-organic framework electrodes for sodium ion batteries

The present disclosure is directed to structural supercapacitors and electrodes for structural supercapacitors having high energy storage and high mechanical characteristics and methods of making the structural supercapacitors and electrodes. The structural supercapacitors can include a solid electrolyte and carbon fiber electrodes comprising carbon nanotubes, surface functionalized redox-active moieties, and/or a conducting polymer.

Enhanced structural supercapacitors

Redox flow batteries including a half-cell electrode chamber coupled to a current collecting electrode are disclosed herein. In a general embodiment, a separator is coupled to the half-cell electrode chamber. The half-cell electrode chamber comprises a first redox-active mediator and a second redox-active mediator. The first redox-active mediator and the second redox-active mediator are circulated through the half-cell electrode chamber into an external container. The container includes an active charge-transfer material. The active charge-transfer material has a redox potential between a redox potential of the first redox-active mediator and a redox potential of the second redox-active mediator. The active charge-transfer material is a polyoxometalate or derivative thereof. The redox flow battery may be particularly useful in energy storage solutions for renewable energy sources and for providing sustained power to an electrical grid.
