Zusammenfassung:An electrode for a rechargeable lithium battery includes a current collector and an active material layer on the current collector, the active material layer including an active material and carbon nanotubes, and the carbon nanotubes having a Raman R value of about 0.8 to about 1.3 and an average length of about 40 μm to about 250 μm. The Raman R value refers to an intensity ratio R=Id/Ig obtained from a peak intensity (Ig) (G, about 1580 cm−1) and a peak intensity (Id) (D, about 1350 cm−1) in a Raman spectrum analysis.
