Method for opening an electrochemical generator
Procédé d'ouverture d'un générateur électrochimique
Résumé
The invention relates to a method for securing an electrochemical generator (10) comprising a negative electrode (20) containing lithium or sodium and a positive electrode (30), the method comprising the following successive steps: (a) immersing an electrochemical generator (10) in an ionic liquid solution (100) containing a solvent ionic liquid and, optionally, a redox species, referred to as the oxidising species, capable of being reduced on the negative electrode so as to discharge the electrochemical generator; (b) opening the electrochemical generator with an electrically insulative element, opening being performed in the ionic liquid solution.
