Electrochemistry simulations from battery modules to ship hulls
With STAR-CCM+, comprehensive simulations involving electrochemistry are possible, opening up applications such as Li-Ion battery modeling and corrosion modeling.
  • 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.

Li-Ion Battery Modeling

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.

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.

Corrosion Modeling

Corrosion modeling in STAR-CCM+ is possible with the Electrodynamic Potential model, typical applications are modeling cathodic protection on structures such as ship hulls, oil platforms and gas pipes, bridges, and reinforced concrete structures. Using STAR-CCM+, you can optimize the location and size of the sacrificial anodes that prevent corrosion. This process ensures that the level of cathodic protection that a structure receives is most effective in prolonging the life of the structure.
