NON-AQUEOUS ELECTROLYTE SOLUTION ADDITIVE FOR LITHIUM SECONDARY BATTERY, AND NON-AQUEOUS ELECTROLYTE SOLUTION FOR LITHIUM SECONDARY BATTERY AND LITHIUM SECONDARY BATTERY WHICH INCLUDE THE SAME

The present invention relates to an additive for a non-aqueous electrolyte solution of a lithium secondary battery which may suppress dissolution of transition metal by forming a stable film on a surface of a positive electrode, a non-aqueous electrolyte solution for a lithium secondary battery which includes the same, and a lithium secondary battery in which swelling and capacity characteristics at high voltage and during high-temperature storage are improved because dissolution of metallic impurities causing failure in the battery is suppressed by including the non-aqueous electrolyte solution.
