Abstract

The invention relates to a method for preparing batteries (100) to be recycled, having at least the following steps:

comminuting a provided battery (100) to be recycled in order to obtain comminuted material (101), the provided battery (100) to be recycled and/or the comminuted material (101) obtained therefrom being thermally pre-treated in a comminuting chamber (3a) by being heated up to a comminuting temperature (TZ), which is lower than 100° C.;transferring the comminuted material (101) into a drying container (4a) and thermally treating the comminuted material (101) by raising an actual ambient temperature (Tlst) and lowering an actual ambient pressure (plst) in the drying container (4a), in order to heat the comminuted material (101) in the drying container (4a), wherein the actual ambient temperature (Tlst) in the drying container (4a) is set such that the comminuted material (101) is heated to no higher than 200° C., and the actual ambient pressure (plst) in the drying container (4a) is set such that both the low-boiling solvent (LL) as well as the high-boiling solvent (LH) are separated by being evaporated out of the comminuted material (101) at the set actual ambient temperature (Tlst), where the low-boiling solvents (LL) and the high-boiling solvents (LH) are discharged out of the same drying container (4a) during the thermal treatment of the comminuted material (101); andmechanically processing the des thermally treated comminuted material (101).
