Title:
CARBON-COATED LITHIUM-RICH OXIDE, AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/016445
Kind Code:
A1
Abstract:
Disclosed in the present invention are a carbon-coated lithium-rich oxide, and a preparation method therefor and the use thereof. The preparation method comprises the following steps: (1) taking a carbon source solution as a base solution, adding a metal salt solution and a precipitant thereto, mixing same, and subjecting the mixture to a precipitation reaction to obtain a precursor slurry; (2) dehydrating, washing and drying the precursor slurry to obtain a nanoscale precursor; (3) mixing the precursor with a lithium salt to obtain a mixture; and (4) subjecting the mixture to a high-temperature solid-phase reaction in an inert atmosphere to obtain the carbon-coated lithium-rich oxide. The carbon-coated lithium-rich oxide prepared by means of the preparation method for the carbon-coated lithium-rich oxide has relatively good conductivity and stability.
