富锂正极材料Li[Li0.2Mn0.4Fe0.4]O2的表面包覆改性
Surface-coating Modification of Li-rich Cathode Materials Li[Li0.2 Mn0.4 Fe0.4] O2
摘要
Abstract
Li-rich cathode material of Li[Li0.2Mn0.4Fe0.4] O2 was prepared by co-precipitation,and was modified by surface coating with Al2O3.The modified samples were characterized by X-ray diffraction,scanning electron microscopy,and electrochemical tests.It was found that the 4.0%Al2O3 coated Li [Li0.2 Mn0.4 Fe0.4] O2 exhibited a good cycling performance compared with the bare Li [Li0.2 Mn0.4 Fe0.4] O2.The discharge capacity loss of the surface coated Li[Li0.2Mn0.4Fe0.4] O2 after 50 cycling was about 9%.关键词
