Focus on the processability of solid polymer electrolytes
Lithium-Ion batteries (LIBs) have been around since the early 1990’s. But it is only recently that they became world-famous for being an enabler of electric mobility and the conversion from fossil to renewable energy. These batteries comprise a liquid that shuttles ions through a semi-permeable polymer membrane called “separator” during charge and discharge. Brückner’s machine concepts are already serving this fast growing industry with production lines for biaxially stretched polyethylene separators. Despite its maturity though, LIBs are facing issues related to their volatile liquid components that the industry would like to overcome.
