In this work, we report the feasibility to achieve high lithium storage performance of MoOx by controlling its microstructure including specific surface area, doping, and amorphous structure. High-surface-area F-doped amorphous MoOx (a-MoOx) is synthesized by hydrothermal hydrolysis of ammonium molybdate tetrahydrate in a water-ethylene glycol (H2O-EG) mixed solvent. The resultant a-MoOx has a surface area as high as 212.74 m(2) g(-1) and exhibits a hierarchically microporous-mesoporous structure. The electrochemical measurements demonstrate that the high-surface-area F-doped a-MoOx exhibits high capacity and excellent electrochemical stability when used as an anode material for lithium-ion batteries. Some synergistic factors including F-doping, high specific surface area, and porous structure, may be responsible for the good lithium-storage performance.
