Major Contributions
 

1. A 2D composite cathode model is developed to quantitatively capture imperfect contact mechanics in solid-state batteries, accounting for interfacial void formation and inhomogeneous pressure distribution that cause capacity loss during cycling.

2. A phenomenological inverse optimization framework is introduced to extract contact quality parameters from electrochemical data, enabling model-based diagnosis of capacity fade originating from electrode-electrolyte contact degradation.

3. The model demonstrates that external pressure application recovers capacity by restoring contact integrity, providing a predictive tool for pressure management strategies in practical solid-state battery stack engineering.


主要貢獻

1. 開發二維複合正極模型，定量描述固態電池中的不完全接觸力學，考量循環過程中引起容量損失的界面空隙形成與不均勻壓力分佈。

2. 提出現象學逆優化框架，從電化學數據中提取接觸品質參數，實現對電極-電解質接觸退化導致容量衰減的模型診斷。

3. 模型驗證外部壓力施加可通過恢復接觸完整性來恢復容量，為實際固態電池組工程中的壓力管理策略提供預測工具。
