Nonmetallic Phosphorus-Driven Oxygen Vacancy and Electronic Structure Modulation Enhancing Bifunctional Catalytic Activity of Cobalt-Based Spinel Air Electrode for Rechargeable Zn-Air Batteries
{{output}}
Zinc-air batteries (ZABs) have great promise for sustainable energy storage. However, the energy conversion efficiency is limited by the lack of cost-effective bifunctional catalysts for the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). ... ...
