Zusammenfassung:An electrode assembly for a rechargeable lithium battery and a rechargeable lithium battery including the same are disclosed. The electrode assembly for the rechargeable lithium battery includes: a negative electrode including a current collector; a negative active material layer; an organic-inorganic composite layer integrated with the negative active material layer, the negative active material layer including an organic layer and an inorganic layer; and a positive electrode, the negative active material layer including a first layer physically contacting the current collector, the first layer including a first carbon-based negative active material, and a second layer on the first layer, including a second carbon-based negative active material, wherein a DD value of the first layer is about 30% to about 90% of a DD value of the negative active material layer, and the DD values are defined by Equation 1.DD(Degree of Divergence)=(Ia/Itotal)*100  Equation 1
