Abstract
(EN)
The present invention provides: an electrolyte solution composition comprising a propane sulton compound substituted with a specific substituent group, a cyclic fluorocarbonate-based compound, and a nonaqueous solvent; and a secondary battery comprising the electrolyte solution composition. By including the cyclic fluorocarbonate-based compound together with the propane sulton compound substituted with a specific substituent group, the electrolyte solution composition according to the present invention exhibits excellent SEI film-forming ability and HF scavenging capacity, and thus can be improved in its lifespan characteristics and thermostability.
