Title: METHOD FOR PRODUCING AN ELECTRODE UNIT FOR A BATTERY CELL, AND ELECTRODE UNIT
Abstract:
The invention relates to a method for producing an electrode unit for a battery cell, wherein a first active material layer (41, 42) is fixed by means of negative pressure to a vacuum unit (70), and a separator layer (18, 19) is fixed by means of negative pressure on the first active material layer (41, 42), such that a composite layer (60) is formed, which is free of a metal current collector (31, 32), and wherein the composite layer (60) is delivered to a layer stack (50) which contains at least one metal current collector (31, 32). The invention further relates to an electrode unit for a battery cell which is produced by the method according to the invention.
