Abstract

The invention discloses a nickel hydroxide nano array / carbon cloth electrode material and a preparation method thereof. The preparation method comprises the steps of S1, putting cleaned and dried carbon cloth into a first solution composed of concentrated nitric acid and concentrated sulfuric acid, then conducting activating treatment, and obtaining activated carbon cloth after cleaning; S2, immersing the activated carbon cloth in a second solution to obtain a mixed system, wherein the second solution is obtained by dissolving nickel nitrate hexahydrate in absolute ethyl alcohol; and carrying out supercritical drying on the mixed system by using absolute ethyl alcohol to obtain the nickel hydroxide nano array / carbon cloth electrode material. The nickel hydroxide nano array / carbon cloth electrode material prepared by the method has excellent electrochemical performance and mechanical stability, and can be applied to supercapacitors.

Description

Technical field [0001] The present invention belongs to the preparation of supercapacitor electrode material, and more particularly to a nickel hydroxide nanocarchers / carbon cloth electrode material and a preparation method thereof. Background technique [0002] Transition metal oxides, hydroxides, and sulfides have been greatly studied as efficient capacitive materials. In numerous hydroxides, Ni (OH) 2 It has a low cost, high capacity, and natural reserves, is considered to be an excellent album capacitor material. It is worth noting that capacitor materials generally cannot be used directly as a flexible solid-state supercapacitor electrode, which requires a substrate which requires flexible conductive, for example: carbon cloth, graphene, and metal substrate. The carbon flexible substrate has good mechanical strength, high conductivity, light, low cost, has been widely used for flexible energy storage devices. Therefore, will Ni (OH) 2 Composition with the carbon fabric is ...
