A METHOD FOR GENERATING ELECTRICAL ENERGY ELECTROCHEMICALLY WHICH COMPRISES MAINTAINING (1) AN ALKALI METAL ANODE-REACTANT AND (2) A CATHODIC REACTANT-ELECTROLYTE THAT IS (A) ELECTROCHEMICALLY REVERSIBLY REACTIVE WITH CATIONS OF SAID ALKALI METAL AND (B) IN CONTACT WITH A CATHODE ON OPPOSITE SIDES OF AND IN CONTACT WITH A SOLID, HALF-CELL SEPARATOR THAT SEPARATES SAID ANODE-REACTANT AND THE ANODIC HALF-CELL REACTIONS THEREOF FROM SAID CATHODIC REACTANT-ELECTROLYTE AND THE CATHODIC HALF-CELL REACTIONS THEREOF, SAID SEPARATOR COMPRISING A SOLID ELECTROLYTE THAT IS SELECTIVELY-IONICALLY-CONDUCTIVE WITH RESPECT TO CATIONS OF SAID ALKALI METAL WHEN A DIFFERENCE OF ELECTRICAL POTENTIAL IS PROVIDED BETWEEN SAID ANODE-REACTANT AND SAID CATHODE, ELECTRICALLY CONNECTING SAID ANODE-REACTANT AND SAID CATHODE WITH A CONDUCTOR WHICH FORMS A PORTION OF AN ELECTRICAL CIRCUIT AND PROVIDES MEANS FOR ELECTRON FLOW BETWEEN SAID ANODE-REACTANT AND SAID CATHODE, SAID ELECTRICAL CIRCUIT BEING COMPLETED BY IONIC CONDUCTION BETWEEN SAID ANODE-REACTANT AND SAID CATHODE THROUGH SAID CATHODIC REACTANT-ELECTROLYTE AND SAID SOLID ELECTROLYTE, AND MAINTAINING SAID ANODE-REACTANT AND SAID CATHODIC REACTANTELECTROLYTE AT A TEMPERATURE SUFFICIENT TO MAINTAIN BOTH IN MOLTEN STATE AND EFFECT SAID HALF-CELL REACTIONS.
