Preparation and Modification Method of Carbon Fiber Electrode for Composite Structure Supercapacitor
High-performance carbon fiber electrodes can be applied to more electrochemical devices and broaden the appli-cation range of supercapacitors.By optimizing the preparation and modification process,the production cost of carbon fiber electrodes can be reduced,thereby reducing the overall cost of supercapacitors and making them more competitive in the market.In this paper,by analyzing the working principle of composite structural supercapacitors,based on oxidation treatment,electrode coating and chemical vapor deposition,the preparation process of carbon fiber electrodes for compos-ite structural supercapacitors is discussed,and corresponding improvement methods are proposed.By analyzing the effects of modified materials such as carbon nanotubes (CNTs),graphene and metal nanoparticles on the performance of carbon fiber electrodes,and through test comparison,it is confirmed that the composite modified materials have a significant effect on improving the performance of carbon fiber electrodes.Through testing and analysis,the paper is expected to pro-vide some reference for the development of supercapacitors and other electrochemical devices in the future.
