Abstract

Abstract : A two-dimensional multi-physics model of a Na-NiCl2 commercial cell is presented. Thermodynamics, electrode kinetics, transport phenomena, and thermal effects are involved in a system of non-linear partial differential equations. This work sheds new light on mathematical modeling of sodium metal halide cell. Some novel hypotheses are used to simulate the cell dynamic behavior during discharges at various rates and initial temperatures. Implementation and computations are performed with Comsol Multiphysics, and the model performance is validated with experimental data obtained from the FIAMM commercial cell.
