The Application Gallery features COMSOL Multiphysics® tutorial and demo app files pertinent to the electrical, structural, acoustics, fluid, heat, and chemical disciplines. You can use these examples as a starting point for your own simulation work by downloading the tutorial model or demo app file and its accompanying instructions.
Search for tutorials and apps relevant to your area of expertise via the Quick Search feature. Note that many of the examples featured here can also be accessed via the Application Libraries that are built into the COMSOL Multiphysics® software and available from the File menu.
Lithium-ion batteries can have multiple active materials in both the positive and negative electrodes. For example, the positive electrode can have a mix of active materials. These materials can have different design properties (volume fraction, particle size), thermodynamic properties ... Read More
The electrodes of a lithium-ion battery are porous, consisting of an active solid material, a binder, and pores filled with liquid electrolyte. If a force is applied on the porous layers of a battery, this will affect the volume fraction of the electrolyte-filled pores in the electrodes, ... Read More
This example demonstrates the Lithium-Ion Battery, Single-Ion Conductor interface for studying the discharge of a lithium-ion battery with solid electrolyte. The geometry is in one dimension and the model is isothermal. The behavior at various discharge currents and solid electrolyte ... Read More
Side reactions and degradation processes may lead to a number of undesirable effects, causing capacity loss in lithium-ion batteries. Typically, aging occurs due to multiple complex phenomena and reactions that occur simultaneously at different places in the battery, and the degradation ... Read More
Large lithium-ion batteries are widely deployed in electric vehicles and for stationary energy storage applications. In the (stacked) pouch battery cell design, all current exits the cell on the cell "tabs", and as the cell size and power increase, the voltage gradients in the highly ... Read More
How the open-circuit voltage (OCV) of a lithium-ion battery varies with the state of charge is governed by various physical properties such as the thermodynamics of the electrode reactions, the relative capacities of the electrode materials, and the amount of cyclable lithium, but also ...
