▎ 摘　　要

NOVELTY - Silicon-carbon cathode material, comprises carbon, composite silicon particles and a conductive agent, and the carbon, composite silicon particles and conductive agent form a mixture particle, where the composite silicon particle includes a silicon-based core body and a carbon coating layer covering the silicon-based core body, and the carbon coating layer is doped with ceramics. USE - The cathode material is useful for lithium ion battery (claimed). ADVANTAGE - The method ensures that the prepared silicon-carbon cathode material has a stable structure and electrochemical performance, has high efficiency, and saves production costs. The Lithium-ion batteries have excellent rate performance and cycle performance, long life, strong fast charging ability, and stable electrochemical performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: preparing the cathode material; and lithium ion battery.
