Patent

CA 2525664

An IC card includes at least one plastic layer (915), a battery (865) and at least one electronic device (980) embedded in the plastic layer (915). The battery (865) is electrically connected to the electronic device (980) for providing power to the device (980). The battery (865) includes an anode, a cathode, and at least one polymer matrix electrolyte (PME) separator disposed between the anode and the cathode. The PME separator includes a polyimide, at least one lithium salt and at least one solvent all intermixed. The PME is substantially optically clear and stable against high temperature and pressure, such as processing conditions typically used in hot lamination processing or injection molding.

L'invention porte sur une carte à circuit intégré comprenant au moins une couche de plastique, une batterie et au moins un dispositif électronique encastré dans la couche de plastique. La batterie est connectée électriquement au dispositif électronique pour alimenter le dispositif en courant. La batterie comprend une anode, une cathode et au moins un séparateur d'électrolyte de matrice polymère (PME) placé entre l'anode et la cathode. Le séparateur de PME comprend un a polyimide, au moins un sel de lithium et au moins un solvant, le tout étant mélangé. Le PME est sensiblement optiquement clair et stable à haute température et à haute pression telles que les conditions de traitement généralement utilisées dans la laminage à chaud ou le moulage par injection.
