Rechargeable Lithium Batteries

A rechargeable lithium battery that includes a positive electrode including a positive electrode active material layer and a current collector; a negative electrode; and an electrolyte solution is provided. The positive electrode active material layer and the electrolyte solution include an additive, a total amount of the additive included in the positive electrode active material layer and the additive included in the electrolyte solution is at least about 0.1 wt % and at most about 1 wt % based on a total positive electrode active material layer. A boiling point of the additive is greater than about 200° C.
