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.
