Abstract

An additive for a non-aqueous electrolyte, a non-aqueous electrolyte including the same, and a lithium secondary battery including the same are disclosed herein. The additive includes an ionic compound to form a coating film on an electrode surface, thereby preventing gas generation at high temperature, a cell open-circuit voltage (OCV) drop, and a decrease in capacity retention rate, which are caused by elution of metal ions from an electrode. The additive improves durability, performance, and high temperature safety of the battery.
