Title (EN) COMPRESSIBLE AND FLEXIBLE COMPOSITE MATERIAL USEFUL IN PARTICULAR AS A CONSTRUCTION MATERIAL FOR BATTERIES
(FR) MATÉRIAU COMPOSITE COMPRESSIBLE ET FLEXIBLE PARTICULIÈREMENT UTILE EN TANT QUE MATÉRIAU DE CONSTRUCTION POUR BATTERIES
Abstract:
(EN) A layered composite, comprising a) two flexible layers (2,3), each comprising a layer of inorganic fibres and a mica laminate; and b) a compressible layer (1) which comprises an inorganic fibre mat and which is sandwiched between said flexible layers (2,3). The layered composite is useful as thermal or electrical barrier material for insulating individual battery cells (4,5) thermally and/or electrically against each other, or for insulating thermally a battery from an environment. The battery is in particular a lithium-ion battery.
(FR) La présente invention concerne un composite stratifié comprenant : a) deux couches souples (2, 3), chacune comprenant une couche de fibres inorganiques et un stratifié de mica ; et b) une couche compressible (1) qui comprend un mat de fibres inorganiques et qui est prise en sandwich entre lesdites couches souples (2, 3). Le composite stratifié est utile en tant que matériau de barrière thermique ou électrique pour isoler des éléments de batterie individuels (4, 5) thermiquement et/ou électriquement les uns par rapport aux autres, ou pour isoler thermiquement une batterie par rapport à un environnement. La batterie est notamment une batterie au lithium-ion.
