NOVELTY - Preparing nickel(II) hydroxide-carbon nanotube reduced graphene oxide composite material comprises e.g. (a) preparation of graphene oxide-carbon nanotubes (GO/CNTs) mixed solution; (b) weighing a specific amount of nickel(II) nitrate hexahydrate (Ni(NO3)2.6H2O) in 10 ml deionized water according to the mass ratio of graphene oxide-nickel(II) hydroxide(GO:Ni(OH)2) is 1:8, and slowly adding the solution to the above graphene oxide-carbon nanotubes (GO/CNTs) mixed solution in dropwise manner, and stirring for 3-4 hours, (c) carrying out hydrothermal reaction, and (d) vacuum drying. USE - The method is useful for preparing nickel(II) hydroxide-carbon nanotube reduced graphene oxide composite material. ADVANTAGE - The composite material has the electrode material with high specific capacity and good circulation stability, and provides convenience for the optimization preparation of the high-performance and low-cost electrode material of the nickel base battery.
