Liquid metal electrodes are one of the key components of different electrical energy storage technologies. The understanding of transport phenomena behind liquid electrodes is mandatory in order to ensure efficient operation, however it would certainly gain by further investigations. In the present study we focus our attention on the positive electrode of a Li||Bi liquid metal battery. Starting from a real experimental setup, we investigate mass transport with numerical simulations. During the charge of the cell, compositional convection becomes apparent. The time evolution of the fluid flow and the flow structure are studied. First results on compositional convection are presented, highlighting its capability to affect the flow in the positive electrode.
