💡 Novelty & Significance:
Iron polyphthalocyanine as a solid-state redox mediator redirects Li-CO₂ battery chemistry to form Li₂C₂O₄ instead of Li₂CO₃, enabling a 3.2 V discharge plateau beyond the theoretical limit, 28,790 mAh/g capacity, 1400-hour cycling, and −40 to 80°C adaptability. Pouch cells reach 678 Wh/kg, advancing practical high-efficiency Li-CO₂ batteries.
