The properties of all materials of the battery structure are defined on the Constituent Materials tab.

The Temperature defines the temperature during simulation in Kelvin (K), Celsius (°C) or Fahrenheit (°F). The material properties of active materials and electrolyte can strongly depend on the temperature.

This temperature-dependence of the material properties can currently be derived from the entries in the material database only for the electrical conductivity.

However, the temperature-dependent ionic diffusivity and the exchange current density are not yet available in the material database. Consequently, while the electrical conductivity values can be adjusted based on the selected temperature — provided that the temperature dependence is included in the database entry — the other material parameters must be manually modified to ensure consistency with the chosen temperature. To facilitate comparisons of simulations at different temperatures, we recommend duplicating the relevant materials in the database for each new temperature and updating the material properties accordingly.

Material IDs of the structure and the assigned materials are listed on the left under Material.

Material properties are organized into four different subtabs on the right, Solid Density, Fluid Density /Viscosity, Electrochemistry, and Electrical Conductivity.
