Lithium ion battery silicon carbide composite anode material and preparation method thereof

The invention discloses a lithium ion battery silicon carbide composite anode material and a preparation method thereof and aims to solve the technical problem of improving the cycling stability of a silicon carbide cathode. The lithium ion battery silicon carbide composite anode material consists of the following components in percentage by mass: 85 to 75 percent of graphite and 15 to 25 percent of silica particles, wherein the nano silica particles are dispersed on a graphite carrier to form a nuclear shell structure and are 5 to 16 mum in granularity. The preparation method comprises the following steps of: preparing a graphite dispersing agent and a silicon grinding dispersing agent; adding the silicon grinding dispersing agent into the graphite dispersing agent; and performing thermal treatment. When the method is compared with the prior art, silicon atoms are dispersed on a graphite atomic nucleus by a cation-anion charge absorption method, so that the silicon atoms can uniformly wrap the surface of the graphite, the dispersity of silicon is effectively improved in a silicon carbide composite material preparing process, the initial efficiency and the cycling stability of the silicon carbide composite anode material are improved, and a battery using the material as an anode material has relatively high safety, multiplying power performance and cycle performance.
