The study of synthetize and electrochemical properties in LiNi_0.55Co_0.15Mn_0.30O₂ cathode material

In this study, spherical nickel cobalt manganese hydroxide precursor were synthesized by coprecipitation method. The precursor and lithium carbonate were mixed homogeneously by mixing machine, the mixture was calcined at high temperature in oxidizing atmosphere, and got the LiNi0.55Co0.15Mn_0.30O₂ cathode material. By designing reasonable lithium content, calcining time and atmosphere conditions, investigated and studied the condition of calcining temperature, the optimum technological conditions were finally optimized.
