摘　　要：环境污染和能源枯竭等问题对开发新的储能和转换装置提出了更高的需求。具有超高能量密度的Li-O_(2)电池有望成为替代传统化石能源极具潜力的候选。但Li-O_(2)电池滞后的反应动力学带来的实际能量密度低、稳定性不佳及倍率性能差等问题制约了其应用,因此迫切需要开发高效电催化剂来提高其滞后的反应动力学。过渡金属硫族化合物由于其类石墨烯结构特点以及本身优异的催化活性吸引了研究人员的广泛研究。本文介绍了过渡金属硫族化合物材料在非水系Li-O_(2)电池催化剂方面的最新研究进展,包括过渡金属硫化物、硒化物、碲化物以及双过渡金属硫族化合物催化剂对Li-O_(2)电池催化性能提高的影响,阐述了对过渡金属硫族化合物材料进行结构设计构建、相调控以及表面改性的方法,建立了其微观结构与氧还原和氧析出催化活性的联系,最后对过渡金属硫族化合物材料在Li-O_(2)电池中的进一步应用进行了展望。The need for new energy storage and conversion technologies has increased,because environmental pollution and energy depletion took place in modern society.Li-O_(2)batteries with extremely high energy densities have been identified as possible alternatives to traditional fossil fuels.Construction of effective electrocatalysts to improve the lagging reaction kinetics of Li-O_(2)batteries is urgent,since the low practical energy density and poor stability limit their applications.Due to their outstanding catalytic activity and graphene-like structure,transition metal chalcogenides have garnered a lot of attentions and investigation.The current developments of transition metal chalcogenides in Li-O_(2)batteries catalysts were introduced in this review,including transition metal sulfides,selenides,tellurides and bimetallic disulfur compounds.Their microstructures and the catalytic activities of oxygen reduction and precipitation were linked,and the impacts of structural design,phase modulation and surface modification on the electrocatalytic performance for Li-O_(2)batteries were clearly demonstrated.Finally,further applications of transition metal chalcogenides in Li-O_(2)batteries were anticipated.
