A rechargeable lithium battery includes an electrode assembly including a positive electrode, a first separator, a negative electrode, and a second separator that are sequentially stacked. The first separator includes a first substrate including a first side facing the positive electrode and a second side facing the negative electrode. The second separator includes a second substrate including a third side facing the negative electrode and a fourth side facing the positive electrode. At least one of the first side to the fourth side includes an organic layer including an organic material, and at least one of the second side or the third side includes an inorganic layer including an inorganic material.
