Abstract
(EN)
A coating composition is described. The coating composition has a plurality of particles of a solid, ionically conductive polymer material. The solid, ionically conductive polymer material has an ionic conductive greater than 1 x 10-4 S/cm at room temperature, and the solid, ionically conductive polymer material is in a glassy state at room temperature. The coating composition also has a plurality of particles of an electrically conductive material. The electrically conductive material has an electrical conductivity at room temperature greater that 1 x 102 S/cm. The coating composition additionally has a plurality of particles of a binder. The binder holds the particles of the composition to form a cohesive coating. Battery and battery components using the coating composition are also described.

L'invention porte sur une composition de revêtement. La composition de revêtement comprend une pluralité de particules d'un matériau polymère solide conducteur d'ions. Le matériau polymère solide conducteur d'ions a un conducteur d'ions supérieur à 1 x 10-4 S/cm à température ambiante et le matériau polymère solide conducteur d'ions est dans un état vitreux à température ambiante. La composition de revêtement comprend également une pluralité de particules d'un matériau électroconducteur. Le matériau électroconducteur a une conductivité électrique à température ambiante supérieure à 1 x 102 S/cm. La composition de revêtement comprend en outre une pluralité de particules d'un liant. Le liant contient les particules de la composition pour former un revêtement cohésif. La présente invention concerne également une batterie et des composants de batterie utilisant la composition de revêtement.
