Abstract

A rechargeable lithium battery includes a positive electrode, a negative electrode, and a separator between the positive electrode and the negative electrode. The separator includes a substrate having a first side facing the negative electrode and a second side facing the positive electrode. A first layer is positioned on the first side of the substrate and includes an organic material, and a second layer is positioned on the second side of the substrate and includes an inorganic material.
