Abstract: Provided is an electrolyte additive for a lithium ion secondary battery including an organic lithium compound and a hyper-branched structure material. The electrolyte additive enhances the decomposition voltage of the electrolyte up to 5.5 V, and increases the heat endurable temperature by 10° C. or more. The safety of the battery is thus improved.
