Producing bipolar plate for bipolar battery, by producing thermoplastic compound having thermoplastic- and electrically conducting filler material, producing film from thermoplastic compound, and laminating film with metalliferous layer

The method comprises producing a thermoplastic compound, which contains a thermoplastic material and an electrically conducting filler material, producing a film made of thermoplastic compound by producing a hollow-cylindrical block made of thermoplastic compound and by peeling the film from the block, and laminating the thermoplastic compound film with a metalliferous layer. The thermoplastic material contains a fluorothermoplastic material. The thermoplastic compound is produced by dry-mixing thermoplastic powder and electrically conducting filler material. The method comprises producing a thermoplastic compound, which contains a thermoplastic material and an electrically conducting filler material, producing a film made of thermoplastic compound by producing a hollow-cylindrical block made of thermoplastic compound and by peeling the film from the block, and laminating the thermoplastic compound film with a metalliferous layer. The thermoplastic material contains a fluorothermoplastic material. The thermoplastic compound is produced by dry-mixing thermoplastic powder and electrically conducting filler material. The portion of the electrically conducting filler material is 40 wt.% to the thermoplastic compound. The electrically conducting filler material contains conductive pigment, soot, carbon powder and/or graphite. The block is produced from the thermoplastic compound by a hot-pressing process. The thermoplastic compound is pressed in a pressing mold and then heated. During heating, pressure does not exercise on the thermoplastic compound. The thermoplastic compound is cooled under pressure after the heating. An independent claim is included for a bipolar plate for a bipolar battery. Um ein Verfahren zur Herstellung einer Bipolarplatte für eine bipolare Batterie zu schaffen, welches auch in der Großserie zuverlässig und einfach durchführbar ist und verlässlich funktionierende Bipolarplatten liefert, wird ein Verfahren zur Herstellung einer Bipolarplatte für eine bipolare Batterie vorgeschlagen, welches folgende Verfahrensschritte umfasst: - Herstellen eines Thermoplast-Compounds, das mindestens ein Thermoplast-Material und mindestens einen elektrisch leitfähigen Füllstoff enthält; - Herstellen einer Folie aus dem Thermoplast-Compound; - Versehen der Folie aus dem Thermoplast-Compound mit mindestens einer metallhaltigen Schicht.
