BINDER FOR LITHIUM SECONDARY BATTERY AND ELECTRODE USING SAME FOR LITHIUM SECONDARY BATTERY

WIPO Patent Application WO/2024/058450

A1

Provided is a binder for a lithium secondary battery, the binder comprising composite particles with a polytetrafluoroethylene structure coated with an acrylic polymer. A binder for a lithium secondary battery according to one embodiment of the present invention can solve problems, such as agglomeration that may occur during the handling of existing binders, while having excellent properties due to a low thickness variation during electrode manufacturing and high tensile strength thereof. In addition, batteries using such an electrode have improved battery performance
