High-Precision Calender Systems for Lithium-Ion Battery Electrode Manufacturing

Electrode calendaring is one of the most critical process steps in lithium-ion battery manufacturing. The thickness, density and porosity of anode and cathode electrodes directly influence battery performance, energy density and cycle life. Achieving these demanding specifications requires exceptional machine precision under extremely high mechanical loads.

Precision under Extreme Forces
BREYER IONPress calender systems are engineered to combine line loads of up to 4,000 N/mm with thickness accuracies of up to ±1,5 µm. This unique combination enables the reliable production of high-quality battery electrodes while ensuring excellent process stability and repeatability.

Decades of Precision Engineering
For decades, BREYER has been developing and manufacturing high-precision calender systems for demanding industrial applications. This extensive experience has been transferred to battery electrode production, resulting in robust, reliable and highly accurate calender technology designed for the requirements of modern gigafactories and pilot production lines alike.
