Zusammenfassung:A rechargeable lithium battery including a positive electrode, a negative electrode, a separator, and a non-aqueous electrolyte is provided. The positive electrode includes a first positive electrode active material including lithium nickel-based composite oxide in the form of secondary particles as a plurality of primary particles agglomerated. The positive electrode includes a second positive electrode active material including lithium nickel-based composite oxide in the form of single particles. The non-aqueous electrolyte includes an organic solvent, a lithium salt, and an additive, and the additive includes a bicyclic sulfate compound.
