Edge Effects In a Spirally Wound Lithium-Ion Battery
Application ID: 9705
Due to the large differences in length scales in a lithium-ion battery, with the thickness of the different layers typically being several orders of magnitude smaller than the extension in the sheet direction, a lithium-ion battery is often well represented by a one-dimensional model. However, the packing and stacking of the battery may cause edge effects which motivate modeling in higher dimensions.
This model investigates the geometrical effects that occur when constructing a lithium ion battery by spirally winding the active battery components to construct a cylindrical “jelly-roll” battery.
This model example illustrates applications of this type that would nominally be built using the following products:Batteries & Fuel Cells Module
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
