Sodium-sulfur type electrochemical generator has a sodium reservoir consisting of a cylinder (1) of beta or beta double prime alumina, closed at both ends by two discs of alpha alumina (5, 6). This reservoir is immersed inside a metal positive reservoir in the form of a cylinder (15) the ends whereof are connected to the two alpha alumina discs by metal annular connecting members (16, 17) which can be deformed. <IMAGE> |
