Abstract Scope |
The present study includes the fabrication of a unique composite electrode with manganese oxide and molybdenum oxide coated on a vertically-aligned graphene structure on carbon fiber (VGCF). Manganese oxide and molybdenum oxide are known for their excellent electrochemical properties and cost-effectiveness. Highly flexible carbon fibers were first used to fabricate a VGCF structure, which exhibited a high specific surface area of 54.59 m2/g and a large areal capacitance of 166 mF/cm2, in 1M sodium sulfate aqueous electrolyte. To further enhance their charge storage capabilities, manganese oxide and molybdenum oxide were coated via hydrothermal route to fabricate: high performing cathodes and anodes. The composite electrodes thus prepared exhibited multifold enhancement in their charge storage capability. The assembled asymmetric device was further subjected to various mechanical tests including bending, tensile and impact tests. Overall this work demonstrates development of a supercapacitor composite electrode for high flexibility and high strength applications. |
