CATHODE FOR SECONDARY BATTERY, METHOD FOR MANUFACTURING SAME, AND LITHIUM SECONDARY BATTERY INCLUDING SAME

Document Type and Number:

WIPO Patent Application WO/2020/050694

Kind Code:

A1

Abstract:

The present invention provides a cathode for a secondary battery including a cathode active material and a lithium-based alloy. In addition, the present invention provides a method for manufacturing a cathode for a secondary battery, the method comprising: a step for forming a cathode mixture layer including a cathode active material, and forming, on the cathode mixture layer, a coating layer including a lithium-based alloy; or a step for forming a cathode mixture layer by applying, on a cathode current collector, slurry for forming a cathode including a cathode active material and a lithium-based alloy, and then pressing the slurry.
