SILICON-GRAPHITE COMPOSITE, PREPARATION METHOD THEREOF, AND LITHIUM BATTERY ANODE AND LITHIUM BATTERY CONTAINING SILICON-GRAPHITE COMPOSITE

A silicon-graphite composite, a preparation method thereof, and a lithium battery anode and a lithium battery containing the silicon-graphite composite are provided in an embodiment of the disclosure. The silicon-graphite composite includes graphite and a silicon source fiber (20). The silicon source fiber (20) is embedded in an interlayer structure of the graphite. The silicon-graphite composite is used as an anode material of the lithium battery in an embodiment of the disclosure, which may prevent deintercalation and loss of a silicon source.
