Title:
NEGATIVE ELECTRODE FOR LITHIUM SECONDARY BATTERY, METHOD FOR MANUFACTURING SAME, AND LITHIUM SECONDARY BATTERY INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2020/184900
Kind Code:
A1
Abstract:
The present invention pertains to a negative electrode for a lithium secondary battery, a method for manufacturing same, and a lithium secondary battery including same. More specifically, the negative electrode for a lithium secondary battery according to the present invention has a protective layer containing a three-dimensional structure composed of metal and lithium nitride, and thus uniform ionic conductivity and electrical conductivity can be induced on the surface of the negative electrode.
