Molten salts at moderate temperatures (ca. 460-690 K) are investigated as electrolytes in two different electrochemical cells employing Zn and Sn electrodes. The thermodynamics and kinetics are explored in an H-cell design, as an analogue to the conventional galvanic cell, and in a one pot, membrane-free system. Emf-temperature measurements reveal opposing trends between the two designs owing to different redox chemistry at the cathode. The potential of these systems for electrochemical energy storage applications are considered. The simpler, membrane-free design is able to deliver the highest short-circuit current densities due to lower Zn activity in a molten ZnSn alloy.
