Since GeoDict 2024, it is also possible to simulate the charging of all solid state batteries. The geometry is designed in the same way as for batteries with fluid electrolyte, using Design Battery, however we recommend some adjustments afterwards.

The GeoDict material database provides one solid electrolyte material: LPSCl. But you can add your own electrolytes to the database as described here.

For the active material in the battery, the Maximum Exchange Current Density must be defined. For LPSCl, the material NMC811 already provides a Maximum Exchange Current Density.

When you use LPSCl with a lithium reservoir, we recommend to change the Maximum Exchange Current Density to 320 A/m² what is referred by Singh et al., 2023 for the exchange current density between lithium and the solid electrolyte LPSCl. Find more information on charging simulations with solid electrolytes refer to the topic All Solid State Batteries.

To avoid issues in the charging simulation, make sure to reassign the material ID of the separator with the same material ID as for the solid electrolyte, which is also shown in the topic All Solid State Batteries. Since GeoDict 2025, the BatteryDict GUI automatically recognizes this, if you set the electrolyte to solid.
