▎ 摘　　要

NOVELTY - The method involves placing the graphene oxide ethanol dispersion in the tin or antimony precursor solution. The reaction solution is sealed, and the reaction is stirred at 450 r/min for 12\|2 hours at 70\|5?oC, cooled to room temperature after the reaction, cleaned by centrifugation, and freeze-dried. The concentration of the graphene oxide ethanol dispersion is 1 mg/mL. The tin precursor is composed of ammonium molybdate tetrahydrate, stannous chloride dihydrate and thioacetamide in a molar ratio of 4:1:10. The antimony precursor is composed of ammonium molybdate tetrahydrate, antimony chloride and thioacetamide in a molar ratio of 4:1:10. USE - Preparation method of graphene composite amorphous metal base electrode material for sodium/potassium ion battery. Can also be used in lithium ion battery. ADVANTAGE - The method uses tin or antimony-based alloying reaction material with high theoretical capacity and low cost advantage, and uses low temperature solvent heat method and adding heterogeneous element to obtain amorphous ternary sulfide material, so it can greatly improve the volume expansion problem of the alloying material in the reaction process, so as to improve the electrochemical performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a negative electrode material for a sodium/potassium ion battery.
