ELECTRODE LAMINATE COMPRISING ELECTRODES HAVING DIFFERENT AREAS AND SECONDARY BATTERY COMPRISING SAME

摘要

Provided is an electrode laminate comprising: an cathode having an cathode coating layer formed on an cathode power collector; a anode having a anode coating layer formed on a anode power collector; and a porous polymer film interposed between the cathode and the anode, wherein the cathode, the anode, and the porous polymer film are laminated along the height direction with respect to a flat surface such that the anode is disposed at the outmost portion, and the coating area of the cathode coating layer is wider than the coating area of the anode coating layer.
