摘　　要：随着人们环境保护意识的日益增强和能源危机的不断加剧,环保、可持续性的可再生能源已引起人们广泛的关注。钠与锂是同主族元素,具有相似的物理、化学性质,并且钠的自然储量丰富、价格低廉。因此钠离子电池(sodium-ion batteries,SIBs)得到了广泛关注,已迅速发展成为锂离子电池(lithium-ion batteries,LIBs)最有效的替代品。作为SIBs负极材料的金属硒化物(MSe_(x))比其他金属化合物表现出了更高的理论容量,在SIBs中显示出良好的电化学性能。然而,在电池充放电循环过程中,MSe_(x)会出现体积变化巨大、结构粉碎、“穿梭效应”等一系列问题。这些问题都限制了MSe_(x)在SIBs中的进一步发展与应用。该研究从储钠机制的角度出发,对不同反应类型的MSe_(x)负极材料在SIBs中的研究现状进行了综述,详述了不同改性策略对其电化学性能的影响,并对MSe_(x)负极材料在SIBs中面临的挑战及其未来发展进行了总结与展望。With the increasing awareness of environmental protection and the growing energy crisis,environmental protection,sustainability and renewable energy have received great attention.Sodium and lithium have similar physicochemical properties,and with abundant natural reserves and low prices,sodium-ion batteries(SIBs)have rapidly developed into the most effective alternative to lithium-ion batteries(LIBs).Metal selenides(MSe_(x))as anode materials for SIBs exhibit higher theoretical capacity than other metal compounds.However,a series of problems,such as huge volume changes during cycling,structural crushing,and the"shuttle effect"of multiple selenides,have limited the further application of metal selenides in SIBs.In this paper,the current research status of metal selenide anode materials with different reaction types in SIBs is reviewed from the perspective of sodium storage mechanism,and the effects of different modification strategies on their electrochemical performances are described in detail.Finally,the challenges and future development of metal selenide electrode materials in SIBs are summarized and prospected.
