Negative electrode for lithium secondary battery and lithium secondary battery including the same

A negative electrode for a lithium secondary battery, the negative electrode comprising:

• a negative active material layer comprising a negative active material, a first binder, and a conductive agent, wherein the negative active material layer is on a current collector, and wherein negative active material comprises a carbonaceous material, silicon, a silicon alloy, a silicon-carbonaceous material complex, tin, a tin alloy, a tin-carbon complex, aluminum, or a combination thereof;
• and
• a protective layer disposed on the negative active material layer, wherein the protective layer is in direct contact with the current collector and comprises a nonaqueous or aqueous second binder, and an inorganic material,
• wherein, in the protective layer comprising the aqueous second binder and the inorganic material, an amount of the inorganic material is about 65 parts by weight or greater, based on 100 parts by weight of the protective layer, and
• wherein in the protective layer comprising the nonaqueous second binder and the inorganic material, the amount of the inorganic material is in a range of about 5 parts to about 25 parts by weight, based on 100 parts by weight of the protective layer.
