Abstract
This invention relates to the field of anode materials, specifically to a carbon-antimony anode material for lithium-ion batteries and its preparation method. The method involves preparing Schiff base-functionalized carbon quantum dots, dispersing these dots in deionized water to obtain a dispersion, mixing the dispersion with anhydrous ethanol solution containing antimony glycol, stirring the mixture, and collecting the product. The carbon-antimony anode material prepared by this invention exhibits excellent electrochemical performance and can be used as a high-performance lithium-ion battery anode material. It also provides a new approach for the precise construction of high-performance electrode materials.
