🔋 Rest‐Pulse Interphase Reconstruction Enables Capacity Recovery in Aged Lithium‐Ion Batteries
📝 پروتکل استراحت-پالس با بازسازی SEI، بازیابی ظرفیت حدود ۱۰٪ و بازده کولنی ۹۹٫۳٪ را در باتریهای لیتیوم-یونی پیرشده LiFePO4/graphite ممکن میسازد.

💡 Novelty & Significance:
The novelty lies in a Rest-Pulse protocol combining discharged-state rest with a short voltage pulse to reconstruct the graphite-side SEI, recovering inactive Li. It achieves 99.3% Coulombic efficiency and ~10% capacity recovery, exceeding rest alone (~6%). Significance: a non-destructive, proof-of-concept route for reviving aged lithium-ion batteries, though larger-format validation and chemistry-specific optimization remain.
