Battery Separator Line

Since decades, Brückner’s biax lines for capacitor films and recently also used for composite current collector films, are the benchmark in film quality and process stability. The LISIM® technology for simultaneous stretching as well as sequential lines enable the production of extremely thin films of down to 2 µm for highest energy density in EV applications as well as thicker films in the range of 6.8-12 µm for HVDC in power transmission, wind and solar power inverters and all kinds of other electrical capacitor applications. | Brückner’s battery separator film lines are providing with 500 million m² saleable film the highest output in the industry and ensures a long-term competitiveness. For high-puncture resistant, ultra-high stretched (down to a thickness of 5 µm) battery separator films, a dedicated line layout is available.
