Surface Segregation Reconstructing Alloy Substrate for Ultra‐Stable Zinc‐Based Batteries

coin cells achieve ultra-stable 40 000 cycles, while pouch cells exhibit ultra-long 5000-h cycling stability with a 91% capacity retention rate, demonstrating superior stability for practical applications. Combining efficiency, cost-effectiveness, and scalability, this work provides a critical pathway for sustainable development and potential commercialization of AZBs.
