【摘要】 电化学储能由于其便利性和高效能,因而在业界和学术界都引起了广泛的关注。高性能的电极材料作为电化学储能的核心,是当前研究的热点领域之一。过渡金属硫化物/硒化物因其较高的理论比容量,丰富的晶体结构,相对较窄的能带带隙,以及独特的电化学行为,因此成为电化学储能的热门电极材料之一。^[1,2]在这个工作中,我们将介绍最近在过渡金属硫属化合物在电化学储能应用上取得的部分研究成果,主要包括:1)以过渡金属硫属化合物为反应物或者中间产物,制备新颖的高性能电极材料;^[3]2)过渡金属硫属化合物直接作为锂/钠离子电池电极负极材料的电化学性能以及反应机制研究;^[4]3)过渡金属硫属化合物作为锂/钠离子电容器电极材料的电化学性能研究;^[5] 4)过渡金属硫属化合物作为锂/钠离子电池电极固态电解质的研究。^[6]更多还原

【Abstract】 Electrochemical energy storage devices are receiving intense interests both from academia and from industries. Therefore, high-performance electrode materials are highly desirable. Recently, metal sulphides/selenides have been explored as advanced electrodes materials for LIBs/NIBs, due to their diverse structures, moderate bonding between M/S, as well as small bandgap as compared to their oxide counterparts.^[1,2] In this work, we report our recent progresses on metal sulphides/selenides for electrochemical energy storage, which include i) sulfides/selenides as reactants for advanced electrodes;^[3] ii) sulfides/selenides as electrode materials in Li/Na-ion batteries,^[4] iii) sulfides/selenides as electrode materials in Li/Na-ion capacitors,^[5] iv) sulfides/selenides as solid electrolytes in Li/Na-ion batteries.^[6]更多还原
