ELECTRODE FOR SECONDARY BATTERY AND SECONDARY BATTERY COMPRISING THE SAME

摘要

The present invention provides an electrode for a secondary battery which has reduced interface resistance and increased adhesiveness between an electrode current collector and an electrode active material. The present invention relates to: the electrode which includes a multi-layered electrode active material layer in a laminated structure consisting of two layers or more formed on the metal current collector; and the secondary battery which includes the same electrode and thus has excellent cycle properties. According to the present invention, the electrode active material layer in a multi-layered structure which includes binders having different molecular weight is formed on the electrode current collector. Therefore, adhesiveness between the electrode current collector and the electrode active material layer is increased; and the secondary battery with enhanced cycle properties and capacity can be manufactured.
