USE OF A COMPOUND AS AN ADDITIVE OF A NON-AQUEOUS ELECTROLYTE SOLUTION, NON-AQUEOUS ELECTROLYTE FOR LITHIUM SECONDARY BATTERY AND LITHIUM SECONDARY BATTERY INCLUDING THE SAME

The present invention relates to a non-aqueous electrolyte solution additive, a non-aqueous electrolyte solution for a lithium secondary battery including the same, and a lithium secondary battery including the non-aqueous electrolyte solution, and particularly, to a non-aqueous electrolyte solution additive using a Lewis base compound capable of rapidly reacting with an acid, a non-aqueous electrolyte solution for a lithium secondary battery including the same, and a lithium secondary battery in which high-temperature storage durability is improved by including the non-aqueous electrolyte solution.
