Liquid Metal Batteries (LMB) are possible candidates for large-scale energy storage in a national energy grid. The attraction of LMB lies in the fast kinetics at liquid metal-electrolyte interfaces, while the major drawback is their operation sensitivity to liquid motion caused mainly by electromagnetic forces. The concept of LMB bears a close similarity to aluminium electrolytic production cells (AEC). The two liquid layer magnetohydrodynamic effects can be projected to the three liquid layer self-segregated structure of LMB. The trend for commercial AEC is to increase their size instead of operating a large number of parallel small ones. Our aim is to develop a numerical model for the three density-stratified electrically conductive liquid layers using 3d and shallow layer approximation accounting for specific MHD effects during periods of battery charge/discharge. A possibility to reuse infrastructure of an old AEC potline for a large scale LMB facility is discussed.
