Batteries are widely used to power equipment in a huge number of industries. The most commonly used technology is lithium-ion, which boasts a high energy density, long cycle life, and low rate of self-discharge. However, lithium-ion batteries are sensitive to temperature conditions, which can impact their performance. To ensure optimal performance and efficient thermal management, the use of modelling and simulation in the design process is crucial. Modelling and simulation is a powerful tool that can help us understand and predict the behaviour of battery systems while also reducing development time and costs.
The COMSOL® software offers a range of capabilities for building detailed models of battery cells and packs, capturing phenomena such as electrochemistry, species transport, heat transfer, fluid flow, and structural mechanics. Engineers and researchers can access a unique environment for running thermal analyses of battery systems, accounting for heating due to activation losses, Joule heating, conjugate heat transfer, nonisothermal flow, and other coupled phenomena.
In this webinar, we will give an overview of the functionality that COMSOL Multiphysics® offers for battery design and thermal analysis, including thermal runaway. We will demonstrate these capabilities using models at both the battery cell and battery pack levels.

Attendees will learn:

1. How simulation and modelling can enhance the battery development process
2. How a Multiphysics approach enables coupled electrochemical, thermal and fluid-flow analysis for battery systems
3. How thermal runaway can be analysed and optimised through simulation of battery cells and packs
