Abstract

An electrolyte solution for lithium secondary batteries is provided. The electrolyte includes lithium salt, non-aqueous organic solvent, and a compound represented by the following formula (1), wherein R1, R2 and R3 are each independently selected from hydrogen, primary, secondary and tertiary alkyl groups, alkenyl groups, and aromatic groups. base. The compound of the present invention decomposes before the organic solvent of the electrolyte and forms an organic SEI film on the negative electrode, thereby inhibiting the decomposition of the organic solvent of the electrolyte.
