摘要： The present invention relates to an electrode for a lithium secondary battery, a method for preparing the same, an electrode assembly for a lithium secondary battery comprising the same, and a lithium secondary battery comprising the same, wherein the electrode comprises an electrode active material, an aqueous binder, a compound represented by Formula 1, and a compound represented by Formula 2. Formula 1 and Formula 2 are the same as set forth in the specification. The electrode for a lithium secondary battery improves the physical properties of the aqueous binder in a manner whereby a cross-linking reaction material is combined with the aqueous binder, so that the electrode can improve initial charge/discharge efficiency and the life span of a lithium secondary battery, preferably a lithium sulfur battery, and improve the area capacity of the electrode.
