  "textContent": "The present invention relates to a novel electrolyte additive, a non-aqueous electrolyte for a lithium secondary battery comprising the novel electrolyte additive, and a lithium secondary battery comprising the non-aqueous electrolyte. More specifically, the present invention relates to a non-aqueous electrolyte for a lithium secondary battery comprising an additive capable of forming a stable film on an electrode surface. The present invention also relates to a lithium secondary battery comprising such a non-aqueous electrolyte, thereby improving the high-temperature lifespan performance of the lithium secondary battery without deterioration, the resistance of the lithium secondary battery without increasing when the lithium secondary battery is stored at high temperatures, and the performance of suppressing expansion of the volume (thickness) of the secondary battery when the lithium secondary battery is stored at high temperatures.",
