Abstract

La sécurité d'une pile électrochimique qui n'est pratiquement pas sous pression, telle qu'une pile au Li/MnO2, comportant un système de dégazage et de sécurité et un solvant d'électrolyte organique est améliorée en prévoyant, en plus de ce système de dégazage, que le solvant d'électrolyte organique comporte au moins 80 % en volume d'un composant volatil, tel que du diméthoxyéthane, ayant un point d'ébullition compris entre 30 degrés C et 130 degrés C.
