Abstract:
The present disclosure relates to a multilayer electrode and a method of manufacturing the same, and more specifically to a multilayer electrode comprising an electrode collector; and two or more electrode active material layers which are sequentially coated on one surface or both surfaces of the electrode current collector, wherein the electrode active material layers each include a carbon-based material, a binder, and a silicon-based material, wherein in the mutually adjacent electrode active material layers based on the direction of formation of the electrode active material layers, the content of the carbon-based material and the content of the binder in the electrode active material layer located relatively close to the electrode collector are larger than the content of the carbon-based material and the content of the binder in the electrode active material layers located relatively far away from the electrode current collector.
