NOVELTY - 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.    USE - Method for producing a bipolar plate for a bipolar battery, which is useful in hybrid electric vehicles.    ADVANTAGE - The method is capable of easily, simply and reliably producing the bipolar plate with high corrosion resistance, good electrical conductivity, high mechanical stability, high electrochemical resistance and high durability in an environmentally friendly manner thus reliably and effectively operating the bipolar battery with high performance.    DETAILED DESCRIPTION - 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.
