LACTAM-BASED ADDITIVE FOR ELECTROLYTE AND SECONDARY BATTERY COMPRISING THE SAME |
摘要 |
Disclosed is an electrolyte for a secondary battery comprising an electrolyte salt and an electrolyte solvent, the electrolyte further comprising a lactam-based compound substituted with an electron withdrawing group (EWG) at the nitrogen position thereof. The electrolyte allows formation of a firm and dense SEI film on the surface of an anode, minimizes irreversible oxidative decomposition at a cathode, and thus can provide a battery with significantly improved lifespan, stability and high temperature characteristics. |
