英文摘要：

The LiMn1/3Ni1/3Co1/3O2 of lithium-ion batteries cathode materials were prepared by molten salt synthesis method,in which KCl was molten salt,and the LiMn1/3Ni1/3Co1/3O2 has satisfactory electrochemical performance.Scanning Electron Eicroscope（SEM） shows that the product is in uniform and particles in even.XRD results demonstrate that the as-synthesized LiMn1/3Ni1/3Co1/3O2 is layered structure.The charge and discharge test results show the sample has a 3.6V plateau and higher reversible capacity.The LiMn1/3Ni1/3Co1/3O2 cathode synthesized at the temperature of 900℃.AA tape of lithium-ion batteries are made with good electrochemical performance.Its initial specific discharge capacity was 132.9mAh/g（2.75～4.2V,1C rate） of better cycle stability.The discharge capacity was 124.6mAh/g after 50 cycles.The rate of discharge capacity was 93.75 ﹪.
