  • Patent number: 11916197
    Abstract: An electrolyte solution additive for a secondary battery, a non-aqueous electrolyte solution including the same, and a lithium secondary battery including the same are disclosed herein. To be specific, the above non-aqueous electrolyte solution includes the electrolyte solution additive comprising the compound represented by Formula 1: wherein, in Formula 1, R1 and R2 are each independently an unsubstituted or substituted alkylene group having 1 to 5 carbon atoms, and L is a direct bond, —O—, —COO—, —RO—, or —R?COO—, wherein R and R? are each independently an alkylene group having 1 to 10 carbon atoms. The additive has an excellent effect of scavenging a decomposition product generated from a lithium salt.
