Liquid metal batteries, i.e. batteries in which both electrodes as well as the electrolyte are in the liquid state (Fig. 1) are usable for grid-scale energy storage and have received considerable attention recently [4, 5]. A current and comprehensive account focusing on their applicability in future large scale storage systems is provided by Bradwell [1, 2], earlier investigations of the technology were oriented on smaller units and thermally regenerative electrochemical systems, see, e.g., [3].
