摘要：
Layered Li-Cr-Mn-O cathode materials related to the LiCrO2-LiMnO2-Li2MnO3 solid solution have been synthesized by the mixed-hydroxide method. The materials are characterized by X-ray diffraction (XRD) and electrochemical techniques. The XRD patterns reveal that samples are a solid solution of hexagonal and monoclinic structures. The most promising cathode material in terms of high capacity and stable cycling performance exhibits the average discharge capacity of 204 mAh g(-1) between 2.5 and 4.5 V versus Li/Li+.
