摘要： Disclosed are a positive electrode for a rechargeable lithium battery and a rechargeable lithium battery including the same, and the positive electrode includes a current collector including a carbon layer disposed on a substrate; and a positive active material layer disposed on the current collector, wherein the carbon layer has a loading level of 0.5 g/m2 to 3 g/m2. The effects of the carbon layer include improving the high power characteristics and the power density by decreasing the internal resistance of an electrode, and to improve the power density by providing uniform current to the positive electrode. The carbon layer may have a thickness of about 1 μm to about 2 μm. When the carbon layer has a thickness within this range, it may achieve the desired effects of a carbon layer. The carbon layer may include a carbon-based material of artificial graphite, natural graphite, carbon black, acetylene black, ketjen black, denka black, or combinations thereof.
