High-surface-area F-doped amorphous MoOx with high-performance lithium storage properties
2014
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 m2 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.
