Brückner - Battery Separator Films

Brückner Maschinenbau offers sophisticated lines as well as customized machine components for the battery separator production. Customers benefit from our wealth of experience in wide and fast stretching. Our state-of-the-art wet process stands for high production efficiency and consistent film quality. Whereas sequential stretching is the most common concept, simultaneous LISIM® technology is the best solution for the utmost flexibility in the wet process. Separators from Brückner machines have successfully passed all standard battery tests and can be coated with commercially available inorganic particles or according to Brückner’s own ceramic coating recipe and know-how. At the K 2022 Brückner announced a further increase in the previous (already exclusive) line width from 5.5m to over 6m and the associated output increases of over 20%.
