Title
(EN) COMPOSITE ELECTRODE COMPRISING A METAL AND A POLYMER MEMBRANE, MANUFACTURING METHOD AND BATTERY CONTAINING SAME
(FR) ELECTRODE COMPOSITE COMPRENANT UN MÉTAL ET UNE MEMBRANE POLYMÈRE, PROCÉDÉ DE FABRICATION ET BATTERIE LA CONTENANT
Abstract
(EN) The present invention relates to a composite negative electrode based on pure metallic lithium, pure metallic sodium or one of their alloys and a polymer membrane, a method for manufacturing such an electrode, as well as an electrical energy storage system, in particular an electrochemical accumulator such as a secondary (rechargeable) lithium or sodium battery comprising at least one such negative electrode. It is particularly applicable to Lithium-Metal-Polymer or LMPTM batteries.
(FR) La présente invention concerne une électrode négative composite à base de lithium métallique pur, de sodium métallique pur ou de l'un de leurs alliages et d'une membrane polymère, un procédé de fabrication d'une telle électrode, ainsi qu'un système de stockage de l'énergie électrique, notamment un accumulateur électrochimique tel qu'une batterie secondaire (rechargeable) au lithium ou au sodium comportant au moins une telle électrode négative. Elle s'applique tout particulièrement aux batteries Lithium-Métal-Polymère ou LMP TM .
