| titleOfInvention | Nickel-manganese-based positive electrode material precursor and synthesis method of positive electrode material |
| abstract | The invention belongs to the field of preparation of lithium ion battery materials, and particularly relates to a nickel-manganese-based positive electrode material precursor and a synthesis method of a positive electrode material thereof. The synthesis method comprises the steps of 1) adding soluble T salt, soluble nickel salt and soluble manganese salt into deionized water, and preparing metal salt solution according to the proportion; 2) preparing a precipitator solution by taking sodium hydroxide, potassium hydroxide or lithium hydroxide; 3) adding pure water, metal powder or metal oxide into a precipitation reactor, respectively heating a metal salt solution and a precipitant solution, and then adding the heated metal salt solution and the precipitant solution into the precipitation reactor to perform coprecipitation reaction; filtering while the solution is hot; and finally, stirring and washing the filtered precipitate by using deionized water, and performing vacuum drying treatment to obtain the nickel-manganese-based positive electrode material precursor. And mixing the precursor with a lithium source, pre-roasting, and calcining at high temperature to obtain the cathode material with complete layered structure, good crystallization degree, stable electrochemical performance, and charge-discharge capacity of more than 200 mAh/g. |
