Future mass production of battery cells will require a flexible calender concept in order to be able to produce economically and in a forward-looking manner. In 2010, BREYER started with the construction of the first battery calender for cell processing. Recently, the second generation of the calender, BREYER IONPress, went into operation successfully.

The new modular calender is designed for a speed of up to 100 m/min and has the option of quickly exchanging rolls as standard. A clever mechanism allows replacement within a few hours. In the record time of less than 3 hours, both rolls were removed and installed in the BREYER practical test and production readiness was restored. The new system is now available for customer trials at BREYER.

For anode production, the calender can be set up in tandem in the line in order to recompact the electrodes in a second calendering step. The new modular calender concept allows the reverse bending function to be retrofitted. In addition, the system can be supplied with automatic winding machines (auto splice).

The enormous roll feed force in connection with highly compressed special roll steel allows line pressures of up to 4000 N/mm and acts directly on the substrate surface without any detours. This gives its users plenty of reserve to also achieve extreme compaction. Some of the other benefits are fast roll change, adjustable counterbend (optional), high line loads, extremely resilient roller steel, fast and precise gap adjustment, and direct nip measurement. The power flow acts directly on the coating
