Abstract:
A negative electrode for a rechargeable lithium battery includes a current collector, a negative electrode active material layer on the current collector, and an organic-inorganic composite layer on the negative electrode active material layer and integrated with the negative electrode active material layer. The negative electrode active material layer includes a negative electrode active material and a first binder, the organic-inorganic composite layer includes a second binder, and the first binder and the second binder include a copolymer including a structural unit derived from a (meth)acrylonitrile monomer.
