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.
