NEGATIVE ELECTRODE AND METHOD FOR MANUFACTURING SAME
DRIVE
December 3, 2025
Disclosed is a negative electrode, including: a current collector; and a negative electrode active material layer disposed on at least one surface of the current collector, and having a negative electrode active material layer containing an artificial graphite, single-walled carbon nanotubes (SWCNTs) and a binder polymer, wherein the negative electrode active material layer includes a lower layer region facing the current collector, and an upper layer region facing the lower layer region and extended to the surface of the negative electrode active material layer, the content of the single-walled carbon nanotubes is 0.003-0.07 parts by weight based on 100 parts by weight of the lower layer region, the single-walled carbon nanotubes have an average diameter of 0.5-15 nm, and the upper layer region includes no single-walled carbon nanotubes (SWCNTs). A method for manufacturing the negative electrode and a lithium secondary battery including the negative electrode are also disclosed.
