Title:
EASY-TO-PROCESS LITHIUM IRON PHOSPHATE COMPOSITE MATERIAL AND PREPARTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/036911
Kind Code:
A1
Abstract:
Disclosed in the present application are an easy-to-process lithium iron phosphate composite material and a preparation method therefor, which belong to the field of battery materials. By means of the preparation method of the present application, a conductive-polymer-modified lithium iron phosphate composite material is prepared from a specific template material and a modification material. The material not only effectively improves the conductivity of lithium iron phosphate, but can also effectively solve the problems of structural damage and uneven agglomeration likely to occur during the process of processing a positive electrode sheet of a battery by using existing lithium iron phosphate of a composite structure, thereby solving the problem of uneven particle size of a lithium iron phosphate composite material after an electrode sheet is processed.
