Abstract: Energized composites include vertically aligned graphene on carbon fibers (VGCF). The VGCF enhances surface area available for charge storage, acts as templates for depositing other charge storing materials and provides stability for a minimum of 100,000 discharge cycles. The final storage device is in the order of high strength carbon fiber matrix with active material, glass fiber separator with polymer electrolyte and another carbon fiber matrix with active material. To achieve higher voltage or current, devices can be connected in series or parallel, respectively. The whole structure is made into a structural component by infusing epoxy resin. An alternating pattern of energy storage devices allows for the epoxy resin to seep through the whole structure and strongly bind them to make a monolith multifunctional composite. The high strength energized composites can power any electrical devices including electric vehicles, portable electronics, and space vehicles without any tradeoff between energy and structural integrity.

Abstract: A glass fiber-based structural composite offers an alternative or supplement to carbon fibers in areas such as battery storage. Through electroless deposition of conductive materials like copper and nickel, the glass fiber surface is made conducting and functions as a good current collector. By using anode and cathode materials like manganese (II, III) oxide and Zinc, cathode and anode mats on the copper- and nickel-coated glass fibers are created via hydrothermal and electro-deposition methods. In one example application, the anode and cathode mats are in an alternate square patterned arrangement using copper and nickel-coated glass fiber as a current collector. The device, with a capacity of >300 mAh/g at 0.1 A/g is assembled using an alternate system of epoxy and electrolyte. Uncoated pristine glass fiber ladened and patterned with electrolyte are used as a separator. Uncoated pristine glass fiber ladened with epoxy can be used as an insulator between two devices.

Abstract: A dual-function supercapacitor carbon fiber composite stores electrical energy and functions, for example, as the body shell of electric vehicles (EVs). This is achieved with a vertically aligned graphene on carbon fiber electrode, upon which metal oxides were deposited to obtain ultra-high energy density anode and cathode. A high-strength multilayer carbon composite assembly is fabricated using an alternate layer patterning configuration of epoxy and polyacrylamide gel electrolyte. The energized composite delivers a high areal energy density of 0.31 mWh cm−2 at 0.3 mm thickness and showed a high tensile strength of 518 MPa, bending strength of 477 MPa, and impact strength 2666 J/m. To show application in EVs, a toy car body fabricated with energized composite operates using the energy stored inside the frame. Moreover, when integrated with a solar cell, this composite powered an IoT (interne of things) device, showing feasibility in communication satellites.
