Abstract

Thermally-operating regimes of a three-layer liquid metal battery are determined in terms of the aspect ratio. The heat exchange between the battery container and the environment is taken into account. Velocity fields and temperature distribution of the convection state inside the battery are determined from numerical simulations. For a chosen geometry, the identified operating regime result in characteristic charge/discharge time close to half a day.
