Abstract
The present invention relates to a non-aqueous electrolyte additive, and a non-aqueous electrolyte for a lithium secondary battery including the same and a lithium secondary battery, and particularly, to a non-aqueous electrolyte additive having a nitrile group and a propargyl group, and a non-aqueous electrolyte for a lithium secondary battery and a lithium secondary battery, which include the non-aqueous electrolyte additive so that capacity and cycle lifespan characteristics at high temperature can be improved.
