Electronic regulation of Fe-N5 sites via Zn coordination for high-efficiency oxygen reduction and rechargeable zinc-air batteries

Key Points

• High-efficiency oxygen reduction in zinc-air batteries was achieved through electronic regulation.
• Coordination of Zn to Fe-N5 sites resulted in a significant enhancement of catalytic activity.
• Experimental and theoretical methods supported the findings on Fe-N5 modified sites.
• These insights may enable broader applications in energy storage technology.
