Abstract
A method is provided for thermal drying treatment of electrode-separator assemblies having a negative electrode and a positive electrode. The method includes positioning the electrode-separator assemblies in a drying device in an effective range of a plurality of inductors configured to inductively heat the plurality of electrode-separator assemblies. The method further includes applying a vacuum for the thermal drying treatment and supplying a current to the inductors. Exactly one inductor is assigned to each electrode-separator assembly to be dried or more than two electrode-separator assemblies are assigned to an inductor that generates an alternating magnetic field of elongate extension in which the more than two electrode-separator assemblies can be arranged so that they are each exposed to essentially the same magnetic field strength in the alternating field.
