🔋 Catalytic Activity Matching Governs Scaffold–Coating Competition in Silicon Anodes
📝 هماهنگی فعالیت کاتالیستی قالبهای MgSO4 و CaSO4 در CVD، تعادل بین استحکام scaffold و یکنواختی پوشش Si را کنترل کرده و بازدهی آندی سیلیکونی را بهبود میدهد.

💡 Novelty & Significance:
The novelty lies in identifying catalytic activity matching, not maximization, as the key design principle for template-catalyzed CVD. The study reveals that scaffold rigidity and coating uniformity compete for finite carbon, quantified via DFT and H₂-TPR. Matching CaSO₄ activity yields uniform coatings and compliant scaffolds, achieving 91.0% initial Coulombic efficiency and 510 Wh kg⁻¹ full cells.
