Anode composition, anode for lithium secondary battery comprising same, and lithium secondary battery comprising anode

Abstract

A negative electrode composition, a negative electrode including the same, a lithium secondary battery including the negative electrode, and a method of manufacturing the negative electrode composition are provided. The negative electrode composition comprises a silicon-based active material, a negative electrode conductive material, and a negative electrode binder, wherein the silicon-based active material comprises Si and optionally SiOx (0<x<2), and includes 70 parts by weight or more of Si on the basis of 100 parts by weight of the silicon-based active material, a carbon coating layer is formed on the silicon-based active material, the negative electrode binder comprises a rubber-based binder and an aqueous binder, and a content of the rubber-based binder is higher than that of the aqueous binder.
