Title (EN) PAPER CURRENT COLLECTOR, METHOD FOR MANUFACTURING SAME, AND ELECTROCHEMICAL DEVICE COMPRISING PAPER CURRENT COLLECTOR
(FR) COLLECTEUR DE COURANT EN PAPIER ET SON PROCÉDÉ DE FABRICATION, ET DISPOSITIF ÉLECTROCHIMIQUE COMPRENANT UN TEL COLLECTEUR DE COURANT
(KO) 종이 집전체, 이의 제조방법 및 이를 포함하는 전기화학소자
Abstract: front page image
(EN) The present invention relates to a paper current collector, a method for manufacturing same, and an electrochemical device comprising a paper current collector. The paper current collector, according to the present invention, is provided with, on top of a fiber layer containing the nanocellulose fiber, conductive layers comprising a conductive material forming a conductive network with the nanocellulose fiber, and thereby provides the advantages of being lightweight, allowing high energy density for an electrode when manufacturing the electrode, having excellent mechanical flexibility, and of securing electrical physical properties and transparency of the material.
(FR) La présente invention porte sur un collecteur de courant en papier et son procédé de fabrication, et sur un dispositif électrochimique comprenant un tel collecteur de courant. Selon la présente invention, le collecteur de courant en papier comporte, sur le dessus d'une couche de fibres contenant la fibre de nanocellulose, des couches conductrices comprenant un matériau conducteur formant un réseau conducteur avec la fibre de nanocellulose, ce qui permet d'offrir les avantages d'un poids léger, de permettre une densité d'énergie élevée d'électrode lors de la fabrication de l'électrode, de présenter une excellente flexibilité mécanique, et de rendre sûres les propriétés physiques électriques et la transparence du matériau.
(KO) 본 발명은 종이 집전체, 이의 제조방법 및 이를 포함하는 전기화학소자에 관한 것으로, 본 발명에 따른 종이 집전체는 나노 셀룰로오스 섬유를 포함하는 섬유층 상에 나노 셀룰로오스 섬유와 전도성 네트워크를 이루는 도전재가 포함된 도전층을 구비함으로써 무게가 가볍고, 전극 제조 시 전극의 에너지 밀도가 높으며, 기계적 유연성이 우수할 뿐만 아니라, 소재의 전기적 물성과 투명성을 모두 활보할 수 있는 이점이 있다.
