NOVELTY - Atomic layer deposition auxiliary preparation of layered double metal hydroxide (LDH)/carbon composite material involves depositing alumina layer on surface of carbon material by atomic layer deposition method to obtain alumina/carbon composite material, dispersing alumina/carbon composite material into aqueous solution containing metal salt and alkaline salt and obtaining LDH/carbon composite material by hydrothermal reaction. USE - The method is used for atomic layer deposition auxiliary preparing layered double metal hydroxide/carbon composite material in field of energy storage, electromagnetic shielding or anti-corrosion (all claimed). ADVANTAGE - The method is simple; can accurately control the thickness of the LDH and effectively solve the agglomeration defect of LDH; and has wide application value in the field of energy storage, electromagnetic shielding and anti-corrosion.
