Title (EN) A Separator For A Rechargeable Battery
(FR) SÉPARATEUR POUR BATTERIE RECHARGEABLE
Abstract:
(EN) The invention provides a coating or film adapted to be arranged between a separator and at least one electrode of a rechargeable battery. The coating or film comprises a first material capable of forming a porous layer and allowing a passage of ions therethrough; wherein, in response to temperature change, the first material porous layer is adapted to substantially close pores in said first material porous layer to thereby substantially reduce or prevent further passage of ions through the first material.
(FR) La présente invention concerne un revêtement ou un film conçus pour être disposé entre un séparateur et au moins une électrode d'une batterie rechargeable. Le revêtement ou le film comprennent un premier matériau permettant de former une couche poreuse et permettant le passage d'ions à travers ces derniers. En réponse à un changement de température, la première couche poreuse de matériau est conçue pour sensiblement fermer des pores dans ladite première couche poreuse de matériau pour ainsi réduire sensiblement ou empêcher un passage supplémentaire d'ions à travers le premier matériau.
