METHOD AND DEVICE FOR PRODUCING A FUNCTIONAL ELEMENT FOR AN ELECTRODE UNIT OF A BATTERY CELL

The invention relates to a method for producing a functional element (50) for an electrode unit of a battery cell, wherein at least one starting material (51) is provided, and the starting material (51) is compressed in a calender (60) and, during the compressing, sound waves or ultrasonic waves are transferred from the calender (60) into the starting material (51). The invention further relates to a device for producing a functional element (50) for an electrode unit of a battery cell, comprising a calender (60) having at least two rollers (61, 62), wherein at least one sound-wave or ultrasonic-wave generator (65) is provided, which is functionally connected to at least one of the rollers (61, 62). 本发明涉及一种用于制造电池组电池的电极单元的功能元件（50）的方法，其中提供至少一种原材料（51），而且在压延机（60）中对所述原材料（51）进行压缩，而且其中在所述压缩期间将声波或超声波从所述压延机（60）传输到所述原材料（51）中。本发明也涉及一种用于制造电池组电池的电极单元的功能元件（50）的设备，所述设备包括具有至少两个辊子（61、62）的压延机（60），其中设置至少一个声波或超声波发生器（65），所述至少一个声波或超声波发生器与所述辊子（61、62）中的至少一个辊子保持功能连接。
