BREYER IONPress 800 calender for compacting coated electrode foil
A range of technologies and process steps are required for the complete production of high-performance lithium batteries. BREYER has focused on the calendering process in this production chain.
During the calendering process, necessary properties such as increased power density, optimized electron transport, and improved contact between particles must be achieved.
With our calender, you can test your specific material and process specifications.
