| titleOfInvention | Preparation method of porous nickel cobaltate/graphene nano composite electrode material |
| abstract | The invention relates to a preparation method of a porous nickel cobaltate/graphene nano composite electrode material, belonging to the field of preparation of new energy materials. Aiming at the defects that the cost of the porous nickel cobaltate prepared by the existing hydrothermal method and the composite material is high and the porous nickel cobaltate is not suitable for large-scale industrial production. The invention takes polymer gel with a three-dimensional network structure synthesized in situ as a template, and obtains the porous nickel cobaltate/graphene nano composite electrode material with the pore diameter and the grain size both in nano level through closed reaction and low-temperature calcination. The basic process is that a reticular polymer formed by in-situ polymerization of micromolecular organic matter under a certain condition is utilized, aqueous slurry containing soluble metal salt, urea and graphene is directly changed into wet gel, the urea is hydrolyzed at a certain temperature, precipitation reaction is carried out in a three-dimensional network, and finally, the porous nano composite electrode material is obtained through drying and calcining and is applied to the high-performance supercapacitor electrode material. The preparation method has the advantages of simple process, energy conservation, environmental protection and easy industrial production. |
