资源简介：
This study aims to investigate the stripping behavior of sodium (Na) anodes in solid-state batteries (SSBs) using Dark-Field X-ray Microscopy (DFXM) at ID03. A novel operando cell with dynamic pressure control will enable real-time tracking of individual Na grains during stripping and re-plating under varying current densities (0.1,1 mA/cm²) and stack pressures (0,10 MPa). By identifying where grains shrink and how pressure influences pore formation, we will provide critical insights into interfacial stability and performance degradation. These findings will inform strategies to optimize Na anodes, mitigate contact loss, and enhance SSB longevity.
