Abstract

The invention provides a rechargeable high temperature electrochemical storage cell having a molten alkali metal anode and a cathode separated from the anode by a ceramic solid electrolyte separator which is a conductor of ions of the anode. The separator has, in contact with its surface exposed to the alkali metal of the anode, a lining of material which is porous to and permeable by the molten alkali metal of the anode. The molten alkali metal of the anode, when in contact with the surface of the material of the lining, exhibits a contact angle of at least 90.degree. with respect to the surface of the lining material.
