Abstract
(EN)
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.
(FR)
L'invention concerne un stratifié d'électrodes comprenant : une cathode ayant une couche de revêtement de cathode formée sur un collecteur de courant de cathode ; une anode ayant une couche de revêtement d'anode formée sur un collecteur de courant d'anode ; et un film polymère poreux intercalé entre la cathode et l'anode, la cathode, l'anode et le film polymère poreux étant stratifiés le long de la direction de hauteur par rapport à une surface plate de sorte que l'anode soit disposée au niveau de la partie la plus extérieure, et l'aire de revêtement de la couche de revêtement de cathode soit plus large que l'aire de revêtement de la couche de revêtement d'anode.
