For these kind of batteries Li-Ion technology is the preferred choice due to the attractive energy density, but they have to meet the highest safety requirements. Here the battery separator film has a significant influence on safety and life time.
During the "Battery Separator Film Demo Days" at the Brückner premises in Siegsdorf, Germany, on July 8th and 9th, international film producers, battery manufacturers and car makers experienced the latest development results live on an exclusive technology centre tour:
- Advancements in the Polyethylen-EVAPORE process for battery separator types for 3C applications (consumer/computer/communication) demonstrated on the pilot line
- Coating of separator film for EV applications
- PP separator film test runs on the laboratory stretching machine
- Special material tests with dedicated equipment
Additionally, several speeches gave a deeper insight into:
- Brückner's latest R&D activities and results for battery separator films
- Brückner's line concepts for the production of battery separator films according to the EVAPORE process
- Battery separator film for EV and power storage applications engineered on Brückner's pilot line
- Requirements of the automotive industry to performance and safety of Lithium-Ion batteries and the conclusions for battery separator film
