摘　　要：为了满足电子市场日益增长的需求,人们研究了许多新材料来取代传统的储能系统电极材料。MoO_(3)是一种理论容量高于石墨烯的电极材料,广泛地应用于金属离子电池和超级电容器。然而,MoO_(3)的本征锂离子/电子电导率较差及转换反应过程中的严重体积效应,严重制约了MoO_(3)的实际应用。通过设计纳米结构、与高导电物质的复合、形成氧空位缺陷、插层复合和掺杂等优化策略可提高MoO_(3)电极材料的电化学性能。综述了MoO_(3)电极材料的主要制备方法,总结了MoO_(3)电极材料的优化方法,并对未来MoO_(3)电极材料的研究工作进行了展望。Numerous new materials have been researched to replace the conventional electrode materials for energy storage systems in order to satisfy the expanding demands of the electronics market.MoO_(3)is an electrode material with a higher theoretical capacity than graphene,which is widely used in metal-ion batteries and supercapacitors.However,the poor intrinsic lithium ion/electron conductivity and the severe bulk effect during the conversion reaction of MoO_(3)severely limit the practical application of MoO_(3).The electrochemical performance of MoO_(3)electrode materials can be improved by optimisation strategies such as designing nanostructures,compositing with highly conductive substances,forming oxygen vacancy defects,intercalation composites and doping.The main preparation methods of MoO_(3)electrode materials are reviewed,the optimisation methods of MoO_(3)electrode materials are summarised,and the future research work on MoO_(3)electrode materials is prospected.
