Zusammenfassung:The invention relates to a mesoporous silicon monoxide negative electrode material with a TiO2/C composite coating layer and a preparation method of the mesoporous silicon monoxide negative electrodematerial. The preparation method comprises the following steps of: carrying out disproportionation reaction on a SiO raw material in a protective atmosphere to obtain disproportionated silicon oxide at the disproportionation temperature of 950-1200 DEG C for 1-10 hours; etching the disproportionated silicon oxide by using hydrofluoric acid, so as to prepare porous SiOx, wherein 0
