Title (EN) ELECTRODE FOR USE IN ELECTROCHEMICAL DEVICE AND MANUFACTURING METHOD THEREFOR
(FR) ÉLECTRODE UTILISÉE DANS UN DISPOSITIF ÉLECTROCHIMIQUE ET PROCÉDÉ DE FABRICATION DE CELLE-CI
(JA) 電気化学デバイス用電極およびその製造方法
Abstract: front page image
(EN)Provided is an electrochemical device such as a nonaqueous-electrolyte battery that exhibits excellent characteristics such as discharge characteristics due to the use of a collector comprising porous metal (e.g., aluminum) bodies to form a thick electrode. The electrode in said electrochemical device, in which an active material is packed into porous metal bodies, is characterized in that said porous metal bodies are sheet-shaped and the electrode is a layered porous body comprising a plurality of single-layer porous metal bodies layered together and electrically connected to each other. Porous aluminum bodies having three-dimensional mesh structures are suitable for said porous metal bodies.
(FR)L'invention concerne un dispositif électrochimique tel qu'une batterie à électrolyte non aqueux qui présente d'excellentes caractéristiques, par exemple des caractéristiques de décharge attribuables à l'utilisation d'un collecteur comprenant des corps en métal poreux (l'aluminium par exemple) afin de former une électrode épaisse. L'électrode dans ledit dispositif électrochimique, dans laquelle un matériau actif est tassé dans des corps en métal poreux, se caractérise en ce que lesdits corps en métal poreux sont en forme de plaque et en ce que l'électrode est un corps poreux stratifié qui comporte une pluralité de corps en métal poreux d'une seule couche stratifiés ensemble et reliés électriquement les uns aux autres. Les corps en aluminium poreux à structures en maille tridimensionnelle conviennent auxdits corps en métal poreux.
(JA)アルミニウムなど金属多孔体を集電体として分厚い電極を形成することにより、放電特性等に優れる非水電解質電池等の電気化学デバイスを提供する。 金属多孔体に活物質が充填された電気化学デバイス用電極であって、前記金属多孔体がシート状であり、複数の単層金属多孔体が積層され、互いに電気的に接続されてなる積層多孔体であることを特徴とする電気化学デバイス用電極とした。金属多孔体が、三次元網目構造を有するアルミニウム多孔体であるとよい。
