Abstract:
A negative electrode for a lithium secondary battery includes: a negative active material disposed on a current collector; a negative active material layer including a first binder and a conductive agent; and a protective layer disposed on the negative active material layer, wherein the protective layer is in direct contact with the current collector and includes a nonaqueous or aqueous second binder and an inorganic material, wherein, in the protective layer including the aqueous second binder and the inorganic material, the amount of the inorganic material may be about 65 parts by weight or greater, based on 100 parts by weight of the protective layer, and wherein the protective layer including the nonaqueous second binder and the inorganic material, the amount of the inorganic material may be in a range of about 5 parts to about 25 parts by weight, based on 100 parts by weight of the protective layer.
