Title (EN) ELECTRODE FOR SECONDARY BATTERY COMPRISING FINE HOLES
(FR) ÉLECTRODE POUR BATTERIE SECONDAIRE COMPRENANT DES TROUS FINS
(KO) 미세 홀들을 포함하고 있는 이차전지용 전극
Abstract:
(EN) The present invention relates to an electrode for a secondary battery, comprising an electrode combined layer comprising an electrode active material formed on one side or both sides of a current collector, wherein the electrode combined layer comprises a plurality of fine holes indented from a vertical cross-sectional surface toward the current collector, and each of the fine holes has a horn shape which gradually decreases in diameter in the direction from the vertical cross-sectional surface toward the current collector.
(FR) La présente invention concerne une électrode pour une batterie secondaire, comprenant une couche combinée d'électrode comprenant un matériau actif d'électrode formé sur un côté ou les deux côtés d'un collecteur de courant, la couche combinée d'électrode comprenant une pluralité de trous fins découpés à partir d'une surface transversale verticale vers le collecteur de courant, et chacun des trous fins a une forme de corne qui diminue progressivement en diamètre dans la direction allant de la surface de section transversale verticale vers le collecteur de courant.
(KO) 본 발명은, 이차전지용 전극으로서, 집전체의 일면 또는 양면에 전극 활물질을 포함하는 전극 합제층이 형성되어 있고; 상기 전극 합제층은 수직 단면상 표면으로부터 집전체 쪽으로 만입된 복수의 미세 홀들을 포함하고 있으며, 각각의 미세홀은 수직 단면상 표면으로부터 집전체 쪽으로 갈수록 직경이 순차적으로 감소하는 뿔(horn) 형상으로 이루어진 것을 특징으로 하는 이차전지용 전극을 제공한다.
