Lithium Battery Designer

Application ID: 51301

This app can be used as a design tool to develop an optimized battery configuration for a specific application. The application computes the capacity, energy efficiency, heat generation, and capacity losses due to parasitic reactions of a battery for a specific load cycle.

Various battery-design parameters consist of: 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:
