摘要:

锂离子电池以其便携、无记忆效应、循环寿命长等特点广泛应用于移动电子设备、电动汽车等领域。负极材料的改进是制备新型高性能锂离子电池的重要环节。具有类石墨烯结构的二硫化钼是极具发展潜力的锂离子电池用负极材料。但纯二硫化钼导电性差、充放电过程中体积膨胀率高,导致其可逆容量低、容量保持率差。复合化与纳米化是解决上述问题的有效途径。综述了近年来用于锂离子电池负极材料的二硫化钼基复合材料研究进展,重点介绍了二硫化钼/碳和二硫化钼/过渡金属化合物体系的形貌特征、比容量、循环稳定性等,并对二硫化钼基负极材料的发展趋势进行了展望。

Abstract:

Lithium-ion batteries are widely applied in portable electronic devices and electric vehicles due to the portability,no memory effect,and long cycle life.The modification of anode materials is an essential component in the manufacture of high-performance lithium-ion batteries.Molybdenum disulfide is a kind of promising anode material for its graphene-like structure.The pure molybdenum disulfide is seriously limited by its low reversible capacity and poor capacity retention,which are caused by poor electrical conductivity and volumetric changes.Composite structure and nanocrystallization with particular morphology are effective approaches to overcome these problems.The research progress of molybdenum disulfide based composite materials used as anode materials for lithium-ion batteries in recent years was reviewed.The morphology,specific capacity,and cycle stability of molybdenum disulfide/carbon and molybdenum disulfide/transition metal compound systems were mainly introduced.Finally,the development trend of molybdenum disulfide-based anode materials was prospected.

Key words: lithium-ion batteries, anode materials, MoS2, composite materials, electrochemical performance
