description The present invention relates to a secondary battery including a cathode, an anode, and lithium salt and non-aqueous organic solvent. Provided is a lithium secondary battery which is characterized by having the cathode includes an aqueous binder and lithium metal phosphorylate as a cathode active material, and having the anode include amorphous carbon as an anode active material. Li1+aM(PO4-b)Xb (1) In the formula, M is one or more kind selected from a group composed of a metal of group 2 to group 12, X is one or more kind of F, S, and n, -0.5
