Study of the influence of co-precipitation process parameters on the physicochemical characteristics of the precursor of the cathode material NCM811
Selection of parameters for the synthesis of precursors for NMC cathode materials is one of the prevailing factors that have a signifi cant impact on the chemical composition, bulk density, surface microstructure, electrochemical characteristics and service life of the resulting cathode materials. In this paper, we study the variation of the mixing rate, pH, concentration of the complexing agent, and the molar ratio of NH3 / sulphate solution concentrations. The strict control during co-precipitation has made it possible to obtain a material with obviously preferable physicochemical characteristics.
