Abstract:Compared with magnesium and aluminum electrolytic cells, lithium electrolytic cell current is small and has a low output, the market demand for lithium metal rising year by year, and the development and design of large current lithium electrolytic cell can provide a reference for the actual use of industry. A two-phase flow model of electrolyte-chlorine gas was established by COMSOL, Euler-Euler two-phase flow model coupled with k-ε model was used to solve the electrolyte velocity, and electric potential, current density, and flow field distribution in the electrolytic cell were analyzed. The results show that there is reflux at the top of the interelectrode space in the electrolytic cell, and the closer to the electrolytic cell, the more obvious the reflux phenomenon. The inner wall of the cell has high turbulence viscosity and eddy current intensity. The electrolyte cycle corresponding to each pair of electrodes has an obvious limit, and the electrolyte cycle is better with the increase in the number of anode and cathode pairs close to the inner wall of the electrolytic cell.
