Title:
ADHESION-STRENGTHENING COMPOSITION, CURRENT COLLECTOR COMPRISING SAME, POSITIVE ELECTRODE INCLUDING SAME CURRENT COLLECTOR, METHOD FOR MANUFACTURING SAME POSITIVE ELECTRODE, AND LITHIUM SECONDARY BATTERY COMPRISING SAME POSITIVE ELECTRODE
Document Type and Number:
WIPO Patent Application WO/2023/136666
Kind Code:
A1
Abstract:
The present invention relates to an adhesion-strengthening composition capable of providing a positive electrode having excellent scratch resistance and adhesiveness and low interfacial resistance, a current collector comprising same, a positive electrode comprising the current collector, a method for manufacturing the positive electrode, and a lithium secondary battery comprising the positive electrode. Provided are an adhesion-strengthening composition comprising a fluorine-based polymer binder, a first water-soluble binder, a second water-soluble binder, and a conductive material, wherein the adhesion-strengthening composition comprises the fluorine-based polymer binder, the first water-soluble binder, and the second water-soluble binder in a specific content; a current collector comprising same; a positive electrode comprising the current collector; a method for manufacturing the positive electrode; and a lithium secondary battery comprising the positive electrode.
