Modelling and simulation (M&S) provides an efficient and low-cost approach to the research and development of batteries. Physics-based models can be used to make predictions, run virtual experiments and even foster new ideas in battery system design.
Battery systems are investigated by a variety of stakeholders with different goals and purposes. Universities, research institutes and national labs often have research programs that aim to fundamentally understand all aspects of battery use. Battery manufacturers have a larger focus on manufacturability, implementation, and use, and original equipment manufacturers are involved in the aspects that relate to battery cell and battery system design. In all of these areas, modelling and simulation can be used to predict, design, optimise and control battery systems.
Modelling and simulation is crucial for understanding the factors that determine a good battery design for a specific application, from the electrodes, electrolyte, separator and current collectors in a battery cell to processes at the molecular, microscopic, battery module and battery stack scales.
In this white paper, you will learn about the chemistries, physics, and design variables that need to be considered at these various scales when using multiphysics modelling to study and design batteries. You will also learn about:
- Porous electrode theory
- Lumped models
- Different modeling scopes in battery R&D
