Non-destructive synchrotron X-ray computed tomography (sXCT) imaging of an ASSB pouch cell showing μ-Si anode, composite cathode, and 3D mud-crack network visualization.

Major Contributions
 

1.Establishment of synchrotron X-ray micro-computed tomography (sXCT) as a rapid, nondestructive, and high-resolution technique for visualizing and quantifying key microstructural features in all-solid-state pouch cells, including porosity, particle size distribution, contact loss, and delamination.

2.Demonstration that integrating sXCT-derived 3D models into multiphysics simulations enables predictive understanding of chemo-mechanical degradation, guiding the design of robust, high-performance solid-state batteries.

3.Advancement of imaging capabilities through computed laminography, multiscale operando imaging, and AI-assisted data processing, improving image quality, temporal resolution, and high-throughput analysis for industry-relevant pouch cell investigations.

主要貢獻
 

1.確立高效非破壞性檢測技術：確立了 同步輻射 X 射線顯微電腦斷層掃描（sXCT） 為一種快速、非破壞性且高解析度的技術。此技術能有效視覺化並量化全固態軟包電池中的關鍵微結構特徵，包含孔隙率（porosity）、粒徑分佈、接觸流失（contact loss）以及層間剝離（delamination）。

2.l結合模擬實現預測性設計：證實將 sXCT 建構的 3D 模型整合至 多物理場模擬（multiphysics simulations） 中，能實現對化學-機械衰退（chemo-mechanical degradation）機制的預測性理解，進而指導設計出更強韌且高性能的固態電池。

3.先進成像能力的拓展：透過引入電腦層析成像（computed laminography）、多尺度原位成像（multiscale operando imaging）及 AI 輔助數據處理，進一步提升了成像能力。這顯著改善了影像品質、時間解析度與高通量分析效率，使其更適用於具工業價值的軟包電池檢測。
