Anode for lithium secondary battery, lithium secondary battery comprising same, and manufacturing method for anode for lithium secondary battery

Abstract

The present disclosure relates to a negative electrode for a lithium secondary battery, including: a negative electrode active material layer including a silicon-based negative electrode active material including SiOx (0≤x<2) and Si nanoparticles; a negative electrode conductive material; and a negative electrode binder, wherein the silicon-based negative electrode active material is in a carbon-uncoated state, an average particle diameter (D50) of the Si nanoparticles is 1 nm or less, and the negative electrode active material layer is pre-lithiated on at least one surface. The present disclosure also relates to a lithium secondary battery including the negative electrode and a method for manufacturing the negative electrode for a lithium secondary battery.
