Electrolyte For Lithium Secondary Battery, And Lithium Secondary Battery Comprising Same

Abstract: Disclosed are: an electrolyte for a lithium secondary battery, which minimizes the movement of anions by forming a cationic polymer backbone, thereby accelerating cations, and can improve mechanical properties and the ability to transfer additional lithium ions by comprising oxide-based ceramics; and a lithium secondary battery comprising same. The electrolyte for a lithium secondary battery comprises: a polymer electrolyte including a hydrocarbon-based polymer compound containing a cationic functional group; a flame-retardant liquid electrolyte; and a crosslinking agent.
