Zusammenfassung:The present disclosure provides a doped ternary precursor, a preparation method therefor, a positive electrode material, and a battery. The method comprises: mixing a fluoride salt and an alkali solution to adjust the pH, and adding a nickel cobalt manganese material, and after the reaction, preparing and obtaining a doped ternary precursor. In the present disclosure, a co-precipitation method is not required when doping metal elements and fluorine for introducing metal elements and fluorine ions, and the purity of a mother liquor system is ensured, thus preventing the corrosion of devices and pipes by co-precipitation processes; in addition, the process is simple, raw materials are easy to obtain, and the present invention is easy to industrialize.
