Solid-state batteries (SSBs) have the potential to overcome the physicochemical limitations of the current market-dominant lithium-ion batteries with liquid electrolytes. However, the interaction between solid mechanics and electrochemical phenomena remains an unresolved challenge in these systems, especially at the cell's internal interfaces [1]. Since isolating different interactions is typically not possible in experimental analyses, these methods usually cannot provide a detailed analysis of their influence. However, physics-based, microstructure-resolved models that account for relevant phenomena of solid mechanics and electrochemistry enable such investigations. They can thus contribute significantly to a better understanding of the complex interactions appearing in SSB cells. This contribution aims to quantify the influence of different electro-chemo-mechanical interface effects, such as delaminations between phases and local mechanical stress at the charge-transfer interface, on SSB cell performance. To achieve this, we extend the electro-chemo-mechanical coupled SSB model presented in [2] by incorporating interaction effects on the charge-transfer kinetics, as, e.g., demonstrated in [3]. The developed framework, therefore, enables systematic studies of the influence of mechanical and electrochemical boundary and operating conditions on cell performance. Based on that, an uncertainty quantification will be performed using the open-source software QUEENS [4] to characterize the impact of interfacial electro-chemo-mechanical interaction phenomena on SSB cell performance.
