Electrode assemblies, and preparation methods thereof, and rechargeable lithium batteries

Abstract

Disclosed are an electrode assembly, a method of preparing the electrode assembly, and a rechargeable lithium battery including the electrode assembly. The electrode assembly includes an electrode current collector, an electrode active material layer on the electrode current collector, and a coating layer located on the electrode active material layer and integrated with the electrode active material layer. The coating layer includes polymer nanofibers. The polymer nanofibers include a fluorine-based polymer and a nitrile-based polymer as a polymer. A dielectric constant of the polymer is greater than or equal to about 0.06 pF/mm3, and the electrical conductivity of the polymer is in a range of about 3.0 μS/mm3 to about 50.0 μS/mm3.
