Abstract

The present invention relates to a non-aqueous electrolyte for a lithium secondary battery including a pyridine-boron-based compound as an additive and a lithium secondary battery including the same, and particularly, to a non-aqueous electrolyte including at least two types of lithium salts and a pyridine-boron-based compound and a lithium secondary battery which has an enhanced effect of suppressing an increase in resistance and generation of gas after being stored at high temperature by including both the non-aqueous electrolyte and a negative electrode including lithium titanium oxide (LTO) as a negative electrode active material.
