| Abstract Scope |
Sodium all-solid-state batteries (NaSSBs) have emerged as promising alternatives to lithium-based systems due to sodium’s abundance and lower cost, offering a more sustainable energy storage solution. Their performance and lifespan are closely linked to microstructural evolution during operation. Charge–discharge cycling can cause void formation, SEI development, and dendritic growth—leading to capacity loss or even failure. Real-time experimental observation of these changes remains challenging, making computational approaches essential for understanding failure mechanisms and improving battery stability.
In this study, we investigate the mechanical effects of dendrite formation during plating–stripping cycles in NaSSBs using mesoscale computation approach, phase-field simullation. This approach captures coupled electrochemical and mechanical interactions in both the anode and solid electrolyte. The influence of different microstructures and external factors, such as stacking pressure, on battery performance were explored. This study aims to offer valuable insights into the microstructural evolution of NaSSBs during operation, thereby guiding future battery development.
