Abstract
A negative electrode for a rechargeable lithium battery includes: a current collector; and a negative active material layer on the current collector. The negative active material layer includes a negative active material including a graphite-silicon composite including a graphite particle, a silicon (Si) particle on a surface of the graphite particle, and a carbon coating layer surrounding the graphite particle on the surface of the silicon (Si) particle. A rechargeable lithium battery includes the negative electrode.
