Abstract
A negative electrode for a rechargeable lithium battery includes a current collector and a negative active material layer disposed on the current collector. The negative active material layer includes a conductive material including a linear-shaped carbon-based material having an average length of about 40 μm to about 250 μm and a dot-shaped carbon-based material, and a negative active material. A mixing ratio of the conductive material and the negative active material is a weight ratio of about 0.1:99.9 to about 2.0:98.0.
