Particle behavior calculation of solid-state battery electrodes

It is said to be difficult to measure the particle behavior of solid-state batteries in actual tests. This analysis is an example of how three types of software, SimLab, Geodict, and ADVENTURECluster, were combined to efficiently perform everything from modeling to structural analysis of an solid-state battery. GeoDict is used to create particle models, SimLab is used to create mesh data, and ADVENTURECluster is used to reproduce particle behavior during charging and discharging.

Background/Issues

Modeling man-hours and computation time are required due to the need to calculate contact between many particles.

Analytical Needs

Calculation of particle behavior during charging and discharging of lithium solid-state batteries, active materials and solid electrolytes.

Determining if damage is caused by injection pressure
