▎ 摘　　要

NOVELTY - Preparation of graphene-based antimony sulfide anode material involves (i) adding the antimony source to the deionized water, stirring it evenly, adding ethylene glycol and stirring to obtain the solution (A), (ii) adding sodium borohydride to the solution (A) obtained in step (i), stirring well and adding polyvinylpyrrolidone and fully dissolving to obtain a solution (B), (iii) adding solution (B) in step (ii) to the lining of the hydrothermal kettle containing sulfur powder to perform hydrothermal reaction, after completing the reaction, separating solid and liquid, washing and drying to obtain antimony trisulfide, and (iv) hydrothermally combining antimony trisulfide and graphite oxide and freeze-drying. USE - Preparation of graphene-based antimony sulfide material used for forming negative electrode for lithium-ion battery (claimed). ADVANTAGE - The method enables simple and economical preparation of graphene-based antimony sulfide material having excellent electrochemical performance, and which is performed in mild condition. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for two-dimensional carbide crystal-based antimony sulfide anode material.
