🔋 Synergistic Electrostatic and Mechanical Anchoring at Cathode–Current Collector Junctions for Durable Sodium‐Ion Batteries

📝 پرایمر کربنی در اتصال کاتد-جمع‌کننده جریان باتری سدیم-یون، با لنگراندازی الکترواستاتیکی و مکانیکی هم‌افزا، پایداری چرخه‌ای و یکنواختی سدیم‌دارشدن را بهبود می‌دهد.

💡 Novelty & Significance:
This work reveals three synergistic mechanisms—mechanical interlocking, strain-accommodating interlayer, and electrostatic bridging—by which carbon primers reinforce cathode–current collector junctions in sodium-ion batteries. It identifies the junction, not bulk conductivity, as the performance bottleneck, and achieves 88.7% capacity retention over 300 cycles, providing a design framework for durable polyanion-based energy storage.
