Abstract: The present invention relates to a barrier for preventing the propagation of a thermal event within a multi-cell battery module, comprising a framework structure and a heat-absorbing material, which comprises water and a component based on biogenic raw materials. Furthermore, the invention relates to a multi-cell battery module and a battery comprising at least one such barrier. Finally, the present invention also relates to a method for preventing the propagation of a thermal event within a multi-cell battery module.

Abstract: The invention relates to an arrangement and a method for the controlled discharge of an energy store using redox shuttle additives and to the use of redox shuttle additives for the controlled discharge of an energy store. The energy store arrangement comprises a storage container with a redox shuttle additive which is dispensed into the electrolytes of the energy store upon triggering a dispensing device such that the energy store is partly or completely discharged, wherein the redox shuttle additive is oxidized on the cathode and reduced on the anode. The redox shuttle additive has a redox potential which is less than or equal to the potential of the partially or completely discharged cathode and greater than or equal to the potential of the partially or completely discharged anode.

Abstract: Energy storage arrangement for safely discharging an energy accumulator with electric poles via which the energy accumulator can be at least discharged, an electrically conductive conductor medium in the form of a fluid or fine-grained bulk material or a mixture of both, a reservoir container which is filled with the conductor medium, a collecting container which is provided for accommodating the conductor medium and which encloses the electric poles of the energy accumulator, and a triggerable discharging device, by means of which, in the case of triggering, conductor medium is discharged from the reservoir container into the collecting container such that the electric poles of the energy accumulator are connected to one another in an electrically conductive fashion via the conductor medium.
