摘　　要：钼基氧化物负极材料结构多变、种类丰富、理论比能量高,有望成为下一代高性能的锂离子电池负极材料.本文简要介绍了钼基氧化物材料(二氧化钼、三氧化钼、三元含钼氧盐)作为锂离子电池负极材料的研究进展.总结了构筑钼基氧化物纳米结构和钼基氧化物复合材料能够提高其作为锂离子电池负极材料的电化学性能.同时,介绍了本研究组在设计合成二氧化钼纳米结构材料和纳米复合材料及开发新型三元钼基氧化物作为锂离子电池负极材料方面的研究进展.开发比容量高、循环性能和倍率性能好的钼基氧化物负极材料仍将是科研工作者面临的重大挑战.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.
