Abstract

A negative electrode for a secondary battery, and a method for manufacturing the same, and more particularly, to a negative electrode for a secondary battery used for a negative electrode of a secondary battery, and a method for manufacturing the same. A negative electrode for a secondary battery may include a carbon-based active material; a conductive material; a silicon-based active material-polymer binder combination including a silicon-based active material, and a polymer binder for suppressing the expansion of the silicon-based active material bonded to a particle surface of the silicon-based active material; a thickener; and a water-based binder.
