Overview of the User’s Guide
The Battery Design Module User’s Guide gets you started with modeling using COMSOL Multiphysics. The information in this guide is specific to this module. Instructions how to use COMSOL in general are included with the COMSOL Multiphysics Reference Manual.
As detailed in the section Where Do I Access the Documentation and Application Libraries? this information can also be searched from the COMSOL Multiphysics software Help menu.
Modeling with Electrochemistry
The Modeling with Electrochemistry chapter discusses a variety of topics, including Fundamentals of Electrochemistry Modeling, Modeling Electrochemical Reactions, Modeling Cyclic Voltammetry, and Postprocessing Your Solution.
The Battery Interfaces
The Battery Interfaces chapter describes the Battery with Binary Electrolyte, Lead–Acid Battery, and Lumped Battery, the Single-Particle Battery and the Lithium-Ion Battery interfaces. Also the Battery Equivalent Circuit model wizard entry is described in this chapter.
The Electrochemistry Interfaces
The Electrochemistry Interfaces chapter describes the Primary Current Distribution, Secondary Current Distribution, Tertiary Current Distribution, Nernst–Planck, Electrode, Shell, and Electroanalysis interfaces.
The AC/DC Interfaces
The AC/DC Interfaces chapter describes the Electrostatics, the Electric Currents and the Electrical Circuit interfaces.
The Chemical Species Transport Interfaces
The Chemical Species Transport Interfaces chapter describes the Transport of Diluted Species, Transport of Concentrated Species, the Transport of Diluted Species in Porous Media, the Surface Reaction and the Reacting Flow interfaces.
The Fluid Flow Interfaces
The Fluid Flow Interfaces chapter describes the Darcy’s Law and Free and Porous Media Flow interfaces, both included under the Porous Media and Subsurface Flow branch.
The Laminar Flow interface is also available and is described in the COMSOL Multiphysics Reference Manual.
Heat Transfer
The Heat Transfer chapter describes how electrochemical heat sources can be coupled to heat transfer, and the theory for how these are calculated.
Solid Mechanics
The Solid Mechanics chapter describes functionality added by the Battery Design Module to the Solid Mechanics interface.
Thermodynamics
This chapter describes the functionality of the Thermodynamics node to define thermo-physical and transport properties.
The Multiphysics Coupling Nodes
The Multiphysics Coupling Nodes chapter describes the coupling nodes available under the Multiphysics node for coupling various electrochemical interfaces using flow, potential, and temperature couplings, for example.
