Method for extinguishing an electrochemical generator in the event of thermal runaway
Procédé d'extinction d'un générateur électrochimique dans le cas d'un emballement thermique
Résumé
Disclosed is a method for extinguishing an electrochemical generator (10), in particular in the event of thermal runaway, the electrochemical generator (10) comprising a first electrode and a second electrode, the first electrode being connected to a first terminal (22) and the second electrode being connected to a second terminal (32) or to the ground of the electrochemical generator, the method comprising a step in which the electrochemical generator (10) is covered by an ionic liquid solution (100), the ionic liquid solution (100) continuously covering the electrochemical generator (10) from the first terminal (22) to the second terminal (32) or from the first terminal (22) to the ground, the ionic liquid solution comprising an ionic liquid and an active species having flame-extinguishing and/or flame-retardant properties.
