| titleOfInvention | Preparation method of niobium-doped lithium manganese aluminum cobalt composite positive pole material |
| abstract | The invention relates to a preparation method of a niobium-doped lithium manganese aluminum cobalt composite positive pole material. The chemical formula of the material is LiMn1-x-y-zAlxCoyNbzO2-aCla. The method comprises the following steps: (1) firstly, preparing a metal ion mixed solution, preparing a KOH solution and an ammonia-water solution, and preparing an H202-containing NaOH solution; reacting the metal ion mixed solution, the ammonia-water solution, and the KOH solution, and aging; and controlling the pH and the basicity of the reaction solution after aging, and then washing, leaching and drying after the reaction is completed to obtain a precursor; and (2) grinding the precursor, lithium oxalate and lithium chloride in a mortar respectively, mixing, drying and sintering, thus obtaining the niobium-doped lithium manganese aluminum cobalt composite positive pole material. By adopting the method for preparing the positive pole material, the precursor of the high-purity high-density ternary composite material is prepared by a wet process, the material is doped with niobium to improve the activity, then the material is doped with chlorine element by a solid phase high temperature process to improve the cycle stability and the rate capability of the material. |
