Abstract This review summarizes the research progresses of Li-Mn-Co-Ni ternary composite cathode material。 This material is owns high specific capacity, relatively low cost, good thermal stability, safety and other advantages, which make it become a highly attractive point in the research of cathode material of battery。 This article concentrates on the material mainly made by NiCl2•6H2O、CoCl2•6H2O、MnCl2•4H2O and l Li2CO3。 In addition, this research investigated the influence to target product (LiNi0。64Co0。16Mn0。2O2 electrode material) ,which is caused by several factors, including the atmosphere in air, nitrogen, argon, the preparation method under coprecipitation method, sol-gel method, high temperature solid state method, and carbon content of 0%、5%、10% which used succinic acid as carbon source。 In the experiment part, we totally synthesized seven samples。 The research also indicated that the sample made in argon under coprecipitation method have a charging ability circulation。 In contrast to these there preparation method, the sample using sol-gel method had a better electrochemical performance, and the highest specific capacity can reach 187mAh·g-1，while the sample particles using high temperature solid state method had a larger size, which lead to a poor electrochemical performance。
