Abstract

The present invention provides a non-aqueous electrolyte and a lithium secondary battery including the same. The non-aqueous electrolyte of the present invention includes a lithium salt, an organic solvent, and an additive. The additive includes a cyclic borate-based compound so as to prevent the decomposition of the non-aqueous electrolyte of the lithium secondary battery in a high-power environment that could lead to negative electrode degradation, or to further improve low-temperature high-rate discharging characteristics, high-temperature stability, overcharging prevention, and high-temperature battery expansion suppression effects.
