摘　　要：二氧化钼具有高密度、高熔点、良好的储锂性能以及结构多样等特点,有望成为代替石墨的新一代锂离子电池负极材料.但二氧化钼电导率低,在锂离子嵌入和脱出过程中体积效应大,面临着倍率性差、首次充放电库伦效率低等问题.碳基材料具有良好的导电性、极大的比表面积和优良的化学稳定性,能够提高二氧化钼负极材料的倍率性能和循环稳定性.本文简要综述了近年来二氧化钼/碳基复合材料(MoO2/C,MoO2/碳纳米管和MoO2/石墨烯)作为锂离子电池负极材料的研究进展,并对复合材料的储锂性能进行了总结.Molybdenum dioxide(MoO 2)is expected to become a new generation of anode material for lithium-ion batteries instead of graphite due to its characteristics of high density,high melting point,good lithium storage performance and variable structures.However,its low conductivity and large volume effect in the process of lithium ion insertion and extraction lead to problems such as poor rate capability and low initial Coulombic efficiency.Carbon-based materials have preeminent electrical conductivity,large specific surface area,and excellent chemical stability,which can improve the rate capability and cycle stability of MoO 2.In this paper,the progress of molybdenum dioxide/carbon composites(MoO 2/C,MoO 2/carbon nanotubes,and MoO 2/graphene)as anode materials for lithium-ion batteries is briefly reviewed,and the improvement of lithium storage performance of molybdenum dioxide composites is summarized.
