- the invention provides that the cell holder has a guide device by means of which the cell holder in the module frame relative to the module frame can be guided.
- the ability of the cell holder to be guided relative to the module frame via the guide device enables a change in volume of the at least one battery cell accommodated by the cell holder to be compensated for by moving the cell holder relative to the module frame, whereby mechanical stress on the battery cell can be kept particularly low when the volume changes.
- the cell holders can be moved relative to the module frame independently of one another via their guide device, whereby the cell holders can be moved relative to one another.

If at least one of the battery cells accommodated in at least one of the cell holders expands, the cell holder accommodating the battery cell and another cell holder resting on the battery cell can be pushed apart by the expansion of the battery cell. As a result When the cell holders are pushed apart, the cell holders move relative to one another, which is made possible by the respective guide devices of the cell holders, via which the cell holders can each be moved relative to the module frame.
- a pressure build-up in the battery cell as a result of the increase in volume can be prevented or at least weakened by the relative movement of the cell holders to one another.
- a pressure load from the at least one battery cell accommodated in the cell holder can thus be kept particularly low.
- the risk of damage to the at least one battery cell accommodated in the cell holder can be kept particularly low.
- a bent edge is provided in which a cell conductor of the battery cell that is received can be bent.
- the bent cell arrester can be connected to a cell arrester of another battery cell, whereby the battery cells can be connected in series or in parallel.

- the cell arrester can be materially connected to the metal insert, in particular it can be welded. A positionally accurate fixing of the cell arrester to the cell holder can be ensured via the material connection. This enables a particularly simple, secure connection of several battery cells which are held in different cell holders.
- the guide device is designed as a dovetail guide.
- the dovetail guide is set up to form a sliding guide with the module frame.
- the dovetail guide is designed to enter into a dovetail connection with the module frame.
- a form-fitting connection between the cell holder and the module frame can be provided via the dovetail connection.
