Abstract
Provided is a lithium secondary battery comprising an anode, a cathode and a non-aqueous electrolyte, wherein the anode includes an aqueous binder, and the non-aqueous electrolyte contains (a) a cyclic anhydride or a derivative thereof; and (b) any one anion receptor selected from the group consisting of a borane compound, a borate compound and mixtures thereof. According to the present invention, a stable SEI film is formed on the anode, and the life characteristics of the battery are improved by controlling the LiF content in the SEI film.
