Abstract
An additive for a non-aqueous solution of a lithium secondary battery, a non-aqueous electrolyte solution including the same, and a lithium secondary battery include the same are disclosed herein. In some embodiments, an additive is a compound represented by Formula 1. The additive may suppress dissolution of transition metal by forming a stable film on a surface of a positive electrode. A lithium secondary battery including the non-aqueous electrolyte solution having the additive has improved swelling and capacity characteristics at high voltage and during high-temperature storage because dissolution of metallic impurities causing failure in the battery is suppressed.
