Lithium Battery Designer
Application ID: 51301
This application can be used as a design tool to develop an optimized battery configuration for a specific application. The app computes the capacity, energy efficiency, heat generation and capacity losses due to parasitic reactions of a lithium-ion battery for a specific load cycle.
In the app various battery-design parameters, such as the geometrical dimensions of the battery canister, the thicknesses of the different components (separator, current collectors and electrodes), the positive electrode material, and the volume fractions of the different phases of the porous materials can be changed. The load cycle is a charge-discharge cycle using a constant current load, which may be different for the charge and discharge stages.
The app also computes the battery temperature (assuming an uniform internal battery temperature), based on the generated heat and the thermal mass. Cooling is defined using an ambient temperature parameter and a heat transfer coefficient.
This application 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.
