Title (EN) A POLYVINYLIDENE FLUORIDE METAL-ADHESIVE COMPOSITION AND AN ELECTRODE FOR A BATTERY
(FR) COMPOSITION ADHERANT A DU METAL ET CONTENANT DU FLUORURE DE POLYVINYLIDENE, ET ELECTRODE DESTINEE A UN ACCUMULATEUR
Abstract:
(EN) A polyvinylidene fluoride metal-adhesive composition where, in a composition composed of vinylidene fluoride homopolymer and vinylidene fluoride copolymer, one or both of these polymers has functional groups which show metal-adhesion, and the vinylidene fluoride copolymer content is from 0.5 to 50 wt.% of the total; and an electrode where, in an electrode for a battery in which the electrode compositional material layer comprising at least electrode active material and binding agent is formed on the surface of a curren collector, there is employed as the binding agent the aforesaid polyvinylidene fluoride metal-adhesive composition.
(FR) L'invention concerne une composition adhérant à du métal, contenant du fluorure de polyvinylidène, et caractérisée en ce que dans une composition comportant un homopolymère de fluorure de vinylidène et un copolymère de fluorure de vinylidène, l'un et/ou l'autre de ces polymères possède(nt) des groupes fonctionnels démontrant un pouvoir d'adhérence sur du métal, et en ce que le pourcentage pondéral du copolymère de fluorure de vinylidène représente 0,5 à 50 % du poids total de la composition. L'invention concerne également une électrode destinée à un accumulateur et caractérisée en ce que l'on a formé la couche de matière composant l'électrode et comprenant au moins un matériau actif d'électrode ainsi qu'un agent de liaison, sur la surface d'un dispositif collecteur de courant, et en ce que l'on a employé en tant qu'agent de liaison ladite composition adhérant à du métal et contenant du fluorure de polyvinylidène.
