| description | Disclosed herein are an electrode assembly having separators the upper ends of which are sealed and a secondary battery including the same. The electrode assembly has a cathode/separator/anode structure that can be charged and discharged. The separators, which protrude beyond the upper ends of the electrodes, are bent in one direction, the separators are heat-treated such that the bent state of the separators is fixed, and an insulative coating layer is formed at the bent surfaces of the separators. Consequently, foreign matter is prevented from being introduced into the electrode assembly, and therefore, the safety of electrode assembly is improved.
L'invention concerne un ensemble électrode qui comprend des séparateurs dont les extrémités supérieures sont scellées, et un accumulateur équipé dudit ensemble. L'ensemble électrode présente une structure cathode/séparateur/anode pouvant être chargée et déchargée. Les séparateurs, qui font saillie au-delà des extrémités supérieures des électrodes, sont courbés dans un sens et sont traités thermiquement de façon que leur état courbé soit maintenu ; et une couche de revêtement isolant est formée sur la surface courbée des séparateurs. L'invention permet d'empêcher l'introduction de corps étrangers dans ledit ensemble électrode, ce qui permet d'améliorer la sécurité de ce dernier. |
