Asymmetric supercapacitor and preparation method and application thereof

The invention discloses an asymmetric supercapacitor and a preparation method and application thereof. The asymmetric supercapacitor comprises a positive electrode, an electrolyte solution and a negative electrode, the positive electrode comprises conductive carbon fiber cloth, a CuCo2O4 nanosheet growing on the surface of the conductive carbon fiber cloth in situ and a delta-MnO2 nanowire growing on the surface of the CuCo2O4 nanosheet in situ, and the negative electrode is conductive carbon fiber cloth loaded with activated carbon, polyvinylidene fluoride and acetylene black. The asymmetric supercapacitor has the advantages of high energy density and power density, large potential window, good cycling stability and the like, and is simple in structure, simple in preparation method, low in production cost and suitable for large-scale industrial application. 本发明公开了一种非对称超级电容器及其制备方法和应用。本发明的非对称超级电容器的组成包括正极、电解质溶液和负极，正极的组成包括导电碳纤维布、原位生长在导电碳纤维布表面的CuCo2O4纳米片和原位生长在CuCo2O4纳米片表面的δ-MnO2纳米线，负极为负载有活性炭、聚偏二氟乙烯和乙炔黑的导电碳纤维布。本发明
