Mechanics of Batteries

This chapter centers on the modeling of materials for energy storage, with a specific focus on Li-ion and Na-ion batteries. Theoretical and computational analyses not only enhance our understanding of how actual batteries behave under various conditions but also have the potential to guide the development of new materials and innovative architectures in conjunction with experimental approaches. Thus, modeling can significantly contribute to the design and prediction of the lifespan of energy storage materials and devices. Batteries exhibit inherent multi-physics and multi-scale characteristics in both space and time. We aim to investigate the mechanical aspects encompassed by multi-physics modeling concepts, methodologies, and simulations at varying scales. In this chapter, we will review the fundamental components of a state-of-the-art electrolytic cell, define their purpose, operational functioning, and mechanical response accounting for various classes of materials.
