  • Lithium Secondary Battery
    Publication number: 20250055036
    Abstract: The present disclosure relates to a high energy density lithium secondary battery having significantly improved high-temperature storage characteristics and lifespan characteristics, which are problematic when a silicon-based negative electrode active material is applied. Specifically, a lithium secondary battery according to an exemplary embodiment includes a positive electrode; a negative electrode facing the positive electrode and including a silicon-based negative electrode active material; and a non-aqueous electrolyte containing a non-aqueous organic solvent including a di-fluoro-based organic solvent and a lithium salt, wherein a content of the di-fluoro-based organic solvent is 5 to 20 vol % with respect to a total volume of the non-aqueous organic solvent.
