Modeling Battery Degradation Mechanisms in COMSOL Multiphysics®
Länge: 46:49
Battery systems face challenges from various degradation mechanisms, which can lead to reduced efficiency, capacity fade, and failure over time. These issues ultimately impact the performance and lifespan of the battery.
In this archived webinar, get an overview of the capabilities of the COMSOL Multiphysics® software for modeling degradation in batteries. You will learn about establishing the ideal behavior of the model using battery scale and model type as well as considering its degradation susceptibility to the following mechanisms:
- Solid electrolyte interphase (SEI) formation
- Mechanical degradation
- Lithium plating
- Gas evolution
- Corrosion
The webinar concludes with an in-depth demonstration of modeling lithium plating in a Li-ion battery.
