<p>An electrochemical cell comprises a cathodic reactant, an anodic region containing liquid sodium, and a solid electrolyte separating the cathodic reactant from the liquid sodium in the anodic region. The anodic region is contained within the solid electrolyte. The cell further comprises a separate reservoir of liquid sodium the anodic region being supplied with liquid sodium from the reservoir. A metal plug is provided in the anodic region. The reservoir is not contained within the solid electrolyte.</p> |
