Abstract
The invention relates to an assembly for storing electrical energy (1), comprising: an envelope comprising a body (10) having at least one side wall (11) and at least one open end, and at least one cover (20) for closing the at least one open end of the body; at least one energy storage element (50) arranged inside the envelope; and an electrolyte solution also inside the envelope. The invention is characterised in that the storage assembly also comprises: a pressure-increasing accelerator (40) for generating an overpressure inside the assembly when the temperature inside the assembly is higher than a temperature threshold, especially at between 120° C. and 140° C.; and means (30) for the local fracturing of the envelope when the pressure inside the envelope is higher than a pressure threshold.
