Recently, as the development of electrical vehicles, unmmaned drones, and transportations using electricity are progressing, researches on not only improvement of performances but also size and efficiency are getting attention. In order to maximize the efficiency of such devices, a battery that functions as energy storage and structure at the same time is required. As to meet such requirements researches on multifunctional battery are highly encouraged thesedays. In this study, carbon fabirc is used for current colloector of both cathode and anode since it is well known to have good electric conductivity and mechanical property. Then, nickel-cobalt and vanadium oxide were grown directly onto carbon fabric by simple hydrothermal methode to complete the anode and cathode respectively. SEM, TEM, XPS, XRD were performed to see morphology and electrochemical properties were examined. Finally, tensile test was performed for mechanical property. |
