Title:
METHOD FOR PREPARING POSITIVE ELECTRODE MATERIAL OF LITHIUM-ION BATTERY
Document Type and Number:
WIPO Patent Application WO/2023/103001
Kind Code:
A1
Abstract:
A method for preparing a positive electrode material of a lithium-ion battery. The method comprises: mixing a mixed lithium salt with a precursor at an Li/TM molar ratio of 1.01-1.1, and sintering same. In the method provided in the present invention, the mixed lithium salt is used as a lithium source for the positive electrode material, and the characteristic of a low eutectic point temperature of the mixed lithium salt is utilized, such that the sintering of the positive electrode material under low-temperature conditions is made possible. While the cost of the raw materials is reduced, the production cost of the positive electrode material is further reduced by means of effectively utilizing low-temperature sintering.
