🔋 Spatially Decoupled Charge Compensation Enables Versatile Cation–Anion Co‐Intercalation in Layered Metal Oxide Cathodes

📝 کاتد اکسید وانادیوم لایه‌ای با لیگاند ملامین، هم‌درج‌شوندگی کاتیون-آنیون را با جداسازی فضایی جبران بار ممکن کرده و عمر چرخه‌ای فوق‌العاده و ظرفیت بالایی در باتری منیزیمی ارائه می‌دهد.

💡 Novelty & Significance:
The novelty lies in a spatially decoupled charge-compensation mechanism using pre-intercalated melamine ligands as anion redox centers while metal sites handle multivalent cation redox, alleviating electrostatic crowding. This enables record cycle life (>36,000 cycles) and high areal capacity in Mg batteries, establishing a versatile platform for multivalent cation–anion co-intercalation in high-performance energy storage.
