钼基氧化物锂离子电池负极材料研究进展

Molybdenum (Mo)-based oxides have aroused much interest as potential anode candidates for lithium-ion batteries, benefitting from both rich chemistry associated with multiple oxidation states of molybdenum and high mass density that is favourable for improving the volumetric energy density of the electrodes. The developments in Mo-based oxides as anode materials in lithium-ion batteries, including molybdenum dioxide, molybdenum trioxide and ternary Mo-based oxides, are introduced briefly in this review. It is concluded that the lithium storage properties are greatly improved in well-designed Mo-based oxide nanostructures and nanocomposites. Moreover, the recent work in our group on the design and preparation of molybdenum dioxide and ternary Mo-based oxide nanostructures as well as nanocomposites as anode materials for lithium-ion batteries are presented in detail. We believe that Mo-based oxides may be used as advanced anode materials in the next-generation lithium-ion batteries, and designing Mo-based anode materials with long cycle life, high reversible capacity, and excellent rate capability is still a great challenge.
