▎ 摘　　要

NOVELTY - Graphene conductive thin film is prepared by formulating 0.01-6 wt.% graphene solution and depositing on metal electrode surface using electron beam vapor deposition machine with vacuum degree of 10-7-10-4 Pa and substrate temperature of 100-500 degrees C. USE - Preparation of graphene conductive thin film for preparing graphene/silicon multilayer composite anode material (claimed) used for lithium battery. ADVANTAGE - Graphene conductive thin film is thin and dense and has high bulk density, large area, flat surface, low contact resistance with metal electrode surface, and electron beam vapor deposition machine has large coating area and fast coating speed. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for production of graphene/silicon multilayer composite anode material which involves alternately coating metal electrode surface greater than or equal to 2 layers of graphene conductive thin films and silicon conductive thin films in which 1st thin film layer close to metal electrode is graphene conductive thin film.
