A rechargeable lithium battery includes an electrolyte, a negative electrode, and a positive electrode. The negative electrode includes a negative active material layer on a negative current collector, and includes a carbon-based negative active material. The negative electrode having a Degree of Divergence (DD) value of about 19 to about 60. The positive electrode includes a positive active material layer and a positive current collector, and includes a positive active material and a porous structured additive. The content of the porous structured additive is about 0.01 wt % to about 2 wt % based on 100 wt % of the positive active material layer.
