The thermally activated chemical source of electric energy is one of the alternative sources. Anodes for such batteries are made of lithium-boron composite. The use of electromagnetic stirring in the technology of production of such material makes it possible to obtain a good quality distribution of boron powder in a lithium melt. As the source of the electromagnetic field two, inductors of travelling magnetic field (TMF) are used. The TMF inductor system allows to generate different flow patterns as one-, two-vortex or more vortex tricky flow structures. The mass transfer in the melt is computed using a three-dimensional k-ω SST turbulence model. A 3D electromagnetic model was used for a Lorenz force density computation. Coupling of the proposed numerical models was performed by means of COMSOL Multiphysics. Tables 1, Figs 7, Refs 14.
