The present disclosure relates to an electrode for a rechargeable lithium battery, containing an electrode current collector, and a multi-layered active material layer. The multi-layered active material layer includes a first active material layer, a second active material layer, and a third active material layer, which are stacked on the electrode current collector. The first active material layer includes a first active material, and the third active material layer includes a second active material. The second active material layer includes first regions that include the first active material, and second regions that include the second active material. The first regions and the second regions are alternatively arranged along a first direction, the first regions extend parallel to each other in a second direction that crosses the first direction, and the second regions extend parallel to each other in the second direction.
