What Can the Battery Design Module Do?
The Battery Design Module extends the COMSOL Multiphysics environment with customized physics interfaces for modeling of batteries. These physics interfaces provide tools for building detailed models of the configuration of the various components of a battery. The physics interfaces include descriptions of the electrochemical reactions and the transport properties that influence the performance in terms of charge-discharge characteristics, capacity, heat production and capacity fade. With this module, you have the perfect tools to investigate the influence of using different materials, geometric configurations, and operating conditions.
The core functionality of the module are the electrochemistry interfaces. Generic electrochemistry interfaces for various types (primary, secondary, and tertiary) current distributions are available, which may be used for modeling both solid nonporous as well as for porous electrodes. In addition to these generic electrochemistry interfaces, the module also contains dedicated battery interfaces.
The tailored physics interfaces mentioned above are also complemented with extended functionality in other physics interfaces for chemical species transport, heat transfer, and fluid flow. The extended functionality for heat transfer and fluid flow may be used, for instance, in battery thermal management models.
A selection of suitable materials are also available in the Battery Material Library. For more detailed information about materials, see Materials in the COMSOL Multiphysics Reference Manual.
Finally, the Application Library available with Battery Design Module includes various tutorials (model examples), for a multitude of different battery chemistries such as:
•
Lithium-ion (Li-ion) batteries
•
Lead–Acid batteries
•
Nickel–metal hydride (NiMH) batteries
•
Vanadium redox flow batteries
•
Soluble lead–acid flow batteries
