Binder for lithium secondary battery and electrode using same for lithium secondary battery

Abstract

A binder includes composite particles with a polytetrafluoroethylene structure coated with an acrylic polymer. The binder can be for a lithium secondary battery according to one embodiment of the present invention, and not only can solve problems such as agglomeration that can occur when handling conventional binders, but also has excellent physical properties such as low thickness deviation and high tensile strength when manufacturing electrodes. In addition, a battery with these electrodes has improved performance, such as improved capacity retention rate.

Dependencies are inferred from the claim text.
