Abstract
A battery housing includes an inner chamber configured to accommodate galvanic cells, in particular lithium-ion cells, which are provided with a cut-out area that can be opened in the event of failure of the cell. In order to prevent, retard and optionally at least partially extinguish a fire in the event of the failure of one or more cells, for example during an accident of an electrically operated vehicle, the inner chamber of the battery housing includes at least one dispenser for dispensing a flame-inhibiting, flame-retarding and/or flame-extinguishing agent. The dispenser has at least one dispenser opening arranged adjacent to a cut-out area of a cell and configured to be opened. The dispenser opening is configured to be opened during a mechanical shock and/or a temperature increase and/or a pressure increase above a predetermined limit value.
