▎ 摘  要

NOVELTY - Preparing anode composite material comprises heating the anode material coated by the catalytic material under the carbon source gas atmosphere, allowing the carbon source gas generating carbon nano-tube on the anode material and adding graphene for coating to obtain the anode composite material. USE - The anode composite material is useful in lithium ion battery (claimed). ADVANTAGE - The anode material has high conductivity and has high rate performance. The method has simple preparation process; is economical and has easy industrial production. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) coating device comprising a shell. The top part of the shell is oppositely and obliquely provided with a first feeding port and a second feeding port which are externally connected with a feeding pipe. The feeding pipe is externally connected with an air inlet branch pipe and the inner top part of the shell is further provided with a rotary fan and the device is used in the graphene coating for preparing the anode composite material; and (2) anode composite material.
