摘　　要：锂离子电池能量密度的提高与其正极材料密切相关,富锂层状氧化物及新型聚阴离子化合物作为下一代高能锂离子电池的正极材料已引起研究工作者的广泛关注.结合本课题组的研究工作,综述了这一领域的最新研究工作进展.重点针对材料结构、物理化学(尤其是电化学)特性、电化学反应机理的原位谱学研究以及材料组成-结构-性能之间的相互关系进行了总结、分析及评述.The capacity of the cathode material is closely correlated with the energy density of a Li-ion battery. In the last few years, high-capacity, lithium-rich layered oxides and novel polyanion compounds have attracted much attention as cathode materials for the next-generation of Li-ion batteries. In this paper, we review the latest developments in these areas, from our group and others. We focus on the structures and physicochemical （especially electrochemical） properties of these cathode materials, and in-situ spectroscopic studies of the mechanisms of electrochemical reactions. The composition-structure-performance relationships of these materials are summarized and analyzed.
