▎ 摘　　要

NOVELTY - Graphene/nickel-cobalt-aluminum-layered double hydroxide composite material is claimed. The composite material is composed of two dimensional sheet and one-dimensional nanorod assembled structure, and carbon nanorod is obtained by dispersing nickel-cobalt-aluminum-layered double hydroxides nano-platelet in nanosheet layer by crimping graphene sheets and wrapping with each other to obtain final product, where diameter of carbon nanorod is 20-120 nm, and length of carbon nanorod is less than 2 mu m. USE - Used as graphene/nickel-cobalt-aluminum-layered double hydroxide composite material. ADVANTAGE - Graphene/nickel-cobalt-aluminum-layered double hydroxide composite material has good dispersibility and simple preparation method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation of graphene/nickel-cobalt-aluminum-layered double hydroxide composite material comprising adding graphene oxide solution into mixed aqueous solution of metal salt and urea, and performing ultrasonic treatment, and then synthesizing graphene/nickel-cobalt-aluminum-layered double hydroxides composite material by hydrothermal method.
