Abstract

Disclosed are a negative electrode for a rechargeable lithium battery and a rechargeable lithium battery including the negative electrode, and the negative electrode for the rechargeable lithium battery includes a negative active material layer comprising a negative active material including a silicon core and an amorphous carbon layer on a surface of the core, wherein an amount of the carbon-based conductive material is about 10 wt% or more based on the total, 100 wt% of the negative active material layer, and the negative electrode has a peak intensity ratio (I₍₁₁₀₎/I₍₀₀₂₎) at a (110) plane relative to a (002) plane of about 1.0 or more measured by XRD.
