Title:

POSITIVE ELECTRODE MATERIAL AND PREPARATION METHOD THEREFOR, AND LITHIUM-ION BATTERY

Document Type and Number:

WIPO Patent Application WO/2024/077965

Kind Code:

A1

Abstract:

Directed at the problem of the absence of a positive electrode material with both a good energy density and ionic conductivity in the prior art, the embodiments of the present application provide a positive electrode material and a preparation method therefor, and a lithium-ion battery, so as to improve the ionic conductivity of a lithium manganese iron phosphate positive electrode material, thereby improving the capacity of the positive electrode material. The positive electrode material comprises an inner layer material and a coating layer that coats the inner layer material, wherein the inner layer material is LiFexMn1-xPO4, and the coating layer comprises Nb2C MXene and carbon, where 0 < x ≤ 0.5.
