dc.description.abstractMechanical characteristics of Li-ion batteries play an important part in the design of electric devices or energy storage systems. Proper mechanical design can increase the safety and the longevity of devices. Apart from external forces, Li-ion batteries also experience internal volume changes due to inherent physical processes, especially volume changes caused by intercalation and deintercalation of lithium ions into electrode materials. Currently, these changes are mainly studied experimentally using complex methods, while numerical simulations of these processes are surprisingly rare. This works presents different numerical approaches for studying internal volume changes in Li-ion batteries. The results show that it is possible to study volume changes at different length scales, but it is necessary to apply a suitable simplification of the model to obtain macroscopic deformation.en
