BREYER IONPress Calander-Technologie

Sophisticated production of electrode foils for lithium-ion batteries

The new generation of the BREYER IONPress calender represents a milestone in the improvement of lithium-ion electrode foil production.

Calender system for lithium-ion electrode production

During the calendering process, required properties such as the increase of the power density, optimized electron transport and improved contact between the particles have to be achieved.

> BREYER offers an advantageous solution that guarantees direct power flow!

BREYER's many years of experience in the field of calender manufacturing made it possible to develop a system that meets the high precision requirements in electrode manufacture. The precise and reliable calender system allows extremely low thickness tolerances.

It is crucial for the operator to be able to set the film thickness reliably, quickly and reproducibly. With the BREYER "fast & easy" gap adjustment technology, adjustment is almost child's play, even in these small dimensions. In connection with the inline thickness measurement, this system allows the construction of an automatic gap control.

The BREYER technology comprises the calendering of the electrode film in the “roll-to-roll” method. The complete line also includes the unwinding of the coated substrate, the inline thickness measurement, surface cleaning and the winding of the electrode film. Upon request, other system components can be integrated.

The machine is equipped with a color touchscreen and process monitoring system for convenient operation.
