Simulating the future, one battery module at a time
STAR-CCM+ offers simulation tools that help you to understand the properties and behavior of Li-ion electrode materials. Since the electrode active materials—especially the cathode active materials—are usually the most expensive components in a Li-ion battery cell, understanding their properties and behavior is crucial for cell manufacturers.
  • A 6 cells module was analyzed in STAR-CCM+. Prismatic wound cells were used and the ohmic heating was solved in the cells connectors. This image shows the temperature distribution on the pack and on the air flow streamlines.

The ability to model the micro-structure of an electrode and predict its electrochemical reactions helps to determine the quality and performance of a cell design. For example, it is possible to determine how tortuous a porous electrode can be, and analyze or parameterize particle size and distribution, both key factors for an electrode.
