Abstract

A negative electrode for a secondary battery, and more particularly, to a negative electrode for a secondary battery used for a negative electrode of a secondary battery. 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 bonded to a surface of the silicon-based active material, wherein the polymer binder suppresses expansion of the silicon-based active material; and a water-based binder.
