NOVELTY - Preparing nickel hydroxide/oxidation graphene/foam nickel composite electrode material comprises (a) using crystalline flake graphite as precursor, preparing to obtain oxidized graphite by chemical peeling, (b) soaking the foam nickel in the graphene dispersion liquid for a period of time, and (c) using three-electrode system, taking foam nickel coated by oxidation graphene substrate, nickel nitrate solution is electro-deposition liquid for electro- deposition, (d) using alkali solution as electrolyte solution, (e) electrochemical activation, (f) using the three electrode system and using alkaline solution as a working electrode, and using nickel hydroxy/oxide /foam graphene composite electrode materials as the working electrode to perform electro-chemical activation. USE - Preparation method of nickel hydroxide composite electrode material used in supercapacitors and lithium batteries. ADVANTAGE - The method is simple to operate, suitable for large-scale processing, and optimizes the preparation of high-activity nickel hydroxide composite electrode material. The obtained electrode material has high battery capacity, and excellent conductivity. The method uses graphene oxide to graphene the foam nickel surface so as to effectively solve the problem of easy agglomeration in the nickel-hydrolyte electrodeposition process, improves the electrochemical activity of the nickel hydrolyte, and prepares the high-active nickel hydrouside material.
