Abstract

The invention belongs to the technical field of capacitor materials, and particularly relates to a nickel hydroxide / cobalt disulfide composite material and a preparation method and application thereof. The preparation method of the nickel hydroxide / cobalt disulfide composite material comprises the following steps: providing carbon cloth, and growing a cobalt-based metal organic framework materialon the surface of the carbon cloth; putting the carbon cloth on which the cobalt-based metal organic framework material grows into an alcoholic solution containing a sulfur source, and carrying out heating treatment to generate cobalt disulfide nanorods on the surface of the carbon cloth; and then depositing nickel hydroxide on the surface of the cobalt disulfide nanorod, and obtaining the nickelhydroxide / cobalt disulfide composite material. The nickel hydroxide / cobalt disulfide composite material obtained by the preparation method has very good electrochemical performance and flexibility, and has relatively high energy density, long cycle performance and very good flexibility when being used as an electrode material in a flexible supercapacitor, so that the nickel hydroxide / cobalt disulfide composite material has very good application value.

Description

technical field [0001] The invention belongs to the technical field of capacitor materials, and in particular relates to a nickel hydroxide / cobalt disulfide composite material and a preparation method and application thereof. Background technique [0002] The rapid development of portable electronic products and the increasing demand for energy systems mean that energy storage systems play more and more roles in human life. In recent years, as an emerging energy storage device, supercapacitors have the advantages of high power density, fast charge and discharge time, and long cycle life. However, their low energy density restricts their further development. [0003] Traditional electric double layer capacitors and pseudocapacitors have low specific capacity. Hybrid capacitors are supercapacitors that integrate battery-like electrode materials with electric double layer electrodes to expand the voltage window, and have high energy density and long cycle life. . However, the...
