Carbon cloth used as flexible supercapacitor electrode material and preparation method and application thereof

The invention discloses carbon cloth used as a flexible supercapacitor electrode material and a preparation method and application thereof. According to the preparation method, carbon cloth is calcined in an oxygen-containing atmosphere through a simple and efficient method, and the flexible carbon cloth supercapacitor electrode material with high specific capacitance is acquired. According to theinvention, the prepared flexible carbon cloth is used as the supercapacitor electrode material, which improves the surface roughness and the specific surface area during the calcination process, andimproves the micropore richness; the electric potential window and the specific capacity are high in an aqueous electrolyte; in the long-term cycle, the capacity is improved compared with the originalone; after 20,000 cycles, the capacity retention rate is 118%, and the stability is great; the original structure and flexibility of the carbon cloth can be maintained after calcination and circulation; and the preparation met
