Title:
POSITIVE ELECTRODE MATERIAL, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/083089
Kind Code:
A1
Abstract:
Provided are a positive electrode material, a preparation method therefor and a use thereof. The positive electrode material comprises a ternary positive electrode material, aluminum tripolyphosphate and a binder. The preparation method comprises: (1) forming a positive electrode material pre-mixture by means of mixing reaction between aluminum tripolyphosphate and the ternary positive electrode material; (2) mixing a colloidal silica sol with the positive electrode material pre-mixture to form a positive electrode material mixture; (3) drying the positive electrode material mixture to obtain a positive electrode material matrix; and (4) sintering the positive electrode material matrix to obtain the positive electrode material. The positive electrode material can be used as a positive electrode material in a lithium-ion battery.
