Electrochemical Analysis

Abaqus/Standard can solve several types of electrochemical problems that are intended for the analysis of battery electrochemistry. You can use these procedures to assess the battery cell's capacity due to different loading conditions, thermal effects, and mechanical effects.

The coupled thermal-electrochemical procedure is intended for the analysis of battery electrochemistry applications that require solving simultaneously for temperature, electric potential in the solid electrode, electric potential in the electrolyte, concentration of ions in the electrolyte, and concentration in the solid particles used in the electrodes. In this procedure, the different fields are solved without any knowledge about the stress/deformation states.

The fully coupled thermal-electrochemical-structural procedure is used to simultaneously solve for displacements, temperature, electric potential in the solid electrode, electric potential in the electrolyte, concentration of ions in the electrolyte, and concentration in the solid particles used in the electrodes. In this procedure, the thermal field and mechanical fields can affect each other. In addition, the concentration in the solid particles used in the electrodes can affect the mechanical fields via eigenstrains caused by particle swelling during the charge/discharge cycle in the battery.
