作为铝离子电池(AIBs)的正极材料,过渡金属硫族化合物(MX_(2)(X=S、Se、Te))具有理论比容量较高和电负性较低等优点,在铝离子电池应用领域极具发展前景。本文以提高过渡金属硫族化合物的储铝性能为目的,综述了过渡金属硫族化合物(MX_(2)(X=S、Se、Te))的储铝机理及其电化学性能的关系,并针对目前过渡金属硫族化合物存在的问题,总结研究者们提出的相应解决方案并归纳此类材料的主要改性技术手段。最后,对过渡金属硫族化合物正极材料的发展方向进行展望,并探讨改善其整体电化学性能的可行策略。
As a promising cathode of aluminum ion batteries(AIBs),transition metal chalcogenides(MX_(2)(X=S,Se,Te))have excellent theoretical specific capacity and lower electronegativity,which endow it with great potential in commercial AIBs.Here,the relationship between the aluminum storage mechanism and the electrochemical properties of the transition metal sulfide compound(MX_(2)(X=S,Se,Te))is summarized.According to the current problems of transition metal chalcogenides,we propose the corresponding solutions proposed by researchers and summarize the main material modification techniques.Finally,the development direction of transition metal chalcogenide cathode materials is prospected,and feasible strategies to improve its overall electrochemical performance are discussed.
