Abstract
An electrode for a rechargeable lithium battery and method of manufacturing a rechargeable lithium battery including the electrode is disclosed. In one embodiment, the electrode includes i) a current collector, ii) a first electrode composition layer provided on a surface of the current collector and iii) a second electrode composition layer farther than the first electrode composition layer from the current collector. Further, each of the first and second electrode composition layers comprises an active material and a conductive material, and wherein the amount of the conductive material of the first electrode composition layer is different from that of the conductive material of the second electrode composition layer. The electrode further includes an additional first electrode composition layer farther than the second electrode composition layer from the current collector and an additional second electrode composition layer farther than the additional first electrode composition layer from the current collector.
