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 &#x3bc;m to about 250 &#x3bc;m 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.

An electrode for a rechargeable lithium battery includes a current collector, an electrode active material layer on at least one surface of the current collector, a carbon-based coating layer between the current collector and the electrode active material layer, the carbon-based coating layer being formed from a carbon-based slurry including a carbon-based material, a first binder, and a thickener. A content of the first binder is about 35 wt % to about 70 wt % based on the carbon-based coating layer.
