Modeling of mass transport is an important step in evaluating lithium-ion battery electrolytes and understanding cell performance. For high-power applications, concentration gradients in the electrolyte lead to limiting currents, which limit the power-density of the battery.
The model has been used for determining a complete set of transport and thermodynamic properties for LiPF6 dissolved in an ethylene carbonate, propylene carbonate and P(VdF-HFP) polymer. The properties were obtained by comparing the model to a set of experimental data.
