磷酸铁锂与镍钴锰酸锂复合材料的电化学性能
Electrochemical characterization of LiFePO4 and LiNi0.5Co0.2Mn0.3O2 composite cathode materials
摘要
Abstract
The synthesis and electrochemical characterization of LiFePO4 and LiNi0.5Co0.2Mn0.3O2 composite cathode materials were studied.The composite cathode materials were obtained by mixing LiFePO4 with LiNi0.5Co0.2Mn0.3O2 according to a certain percentage.The composite materials with the advantages of LiFePO4 and LiNi0.5Co0.2Mn0.3O2 have excellent electrochemical characterization.The properties of the composite materials were characterized and analyzed by X-ray diffraction (XRD),scanning electron microscopy (SEM),charge/discharge test and AC impedance.The results show that the electrochemical characterization of composite materials is more excellent when the mass percentage of LiFePO4 and LiNi0.5Co0.2Mn0.3O2 is 30∶70.关键词
