🔋 Understanding the Role of Lithium Metal Microstructure in Chemo-Mechanical Instability of Solid-State Batteries
📝 مدلسازی مزو-مقیاس نشان میدهد ریزساختار آند لیتیوم، بهویژه اندازه دانه، بر تشکیل حفره و از دست رفتن تماس در فصل مشترک لیتیوم-الکترولیت جامد در حین دشارژ تأثیر میگذارد.

💡 Novelty & Significance:
This study uniquely links polycrystalline Li anode microstructure to void-driven interfacial contact loss in solid-state batteries via a mesoscale model informed by atomics. It shows small grains promote self-diffusion healing, and quantifies how pressure, current, and temperature affect stripping across microstructures. Significance: incorporating microstructure is essential for predicting anode–electrolyte contact evolution and enabling practical areal capacities.
