摘要： An electrolyte for a lithium secondary battery and a lithium secondary battery including the same are provided. The electrolyte may include a lithium salt, an organic solvent, and an additives (e.g., sulfolane, cyclic phosphate, cyclic phosphite) that form a cathode electrolyte interface film to protect the surface of a positive electrode. Utilization of the additives may improve cycle-life characteristics and suppress or reduce increases to resistance during high-temperature storage of the lithium secondary battery.
