Summary:Disclosed in the present invention are a modified silicon-carbon negative electrode material, a preparation method therefor, and an application thereof. The preparation method comprises: (1) mixing a silicon-carbon negative electrode material with a lithium alkoxide solution to carry out a solvothermal reaction; and (2) alcohol washing solid powder obtained after the solvothermal reaction in step (1), and drying the powder to obtain the modified silicon-carbon negative electrode material. The lithium alkoxide solution is formed by mixing metallic lithium with an alcohol solvent. La présente invention concerne un matériau d'électrode négative au silicium-carbone modifié, son procédé de préparation et son application. Le procédé de préparation consiste à : (1) mélanger un matériau d'électrode négative au silicium-carbone avec une solution d'alcoxyde de lithium pour réaliser une réaction solvothermale ; et (2) laver à l'alcool la poudre solide obtenue après la réaction solvothermale à l'étape (1), et sécher la p
