“…The chosen chemistry in this study is Li||Bi, which was experimentally investigated from the electrochemical perspective by Ning et al [10]. Furthermore, there is extensive literature (compared to other electrode pairs) on the thermodynamic properties of Bi -Li alloys [37][38][39][40][41][42][43][44][45][46][47][48], allowing for good estimations. The considered molten salt electrolyte is KCl -LiCl, with a near eutectic composition (41.5 % mol KCl).…”

Liquid Metal Batteries (LMBs) are a promising concept for cheap electrical energy storage at grid level. These are built as a stable density stratification of three liquid layers, with two liquid metals separated by a molten salt. In order to ensure a safe and efficient operation, the understanding of transport phenomena in LMBs is essential. With this motivation we study thermal convection induced by internal heat generation. We consider the electrochemical nature of the cell in order to define the heat balance and the operating parameters. Moreover we develop a simple 1D heat conduction model as well as a fully 3D thermo-fluid dynamics model. The latter is implemented in the CFD library OpenFOAM, extending the volume of fluid solver, and validated against a pseudo-spectral code. Both models are used to study a rectangular 10×10 cm Li||Bi LMB cell at three different states of charge.
