In an electric cell having a solid electrolyte and employing sodium as the iquid anode and sulphur as the liquid cathode, the liquid anode is contained in two compartments separated by a corrosion resistant barrier. Liquid anode is arranged to flow between the compartments through a flow restrictor which permits a rate of flow sufficient to meet the normal charge and discharge requirements of the cell but limits higher rates of flow. One of the compartments has a very limited capacity for liquid sodium and is disposed about one side of the solid electrolyte to define a wicking space to constrain liquid sodium to flow over the solid electrolyte. The other compartment provides a reservoir for containing the bulk of the liquid sodium. In the event of damage to the solid electrolyte, only a very limited amount of liquid sodium is readily available to mix and react with the liquid sulphur.
