High-entropy nanoalloys are reported to be highly efficient and stable bifunctional oxygen catalysts, which are important for the sustainable application of rechargeable zinc-air batteries. However, phase separation is a common issue in the preparation of high-entropy nanoalloys. Herein, a high-entropy nanoalloy was successfully constructed using the molten salt electroreduction method. The bifunctional oxygen overpotential (ΔE) of the catalyst is as low as 0.72 V. The zinc-air battery assembled with this catalyst exhibits exceptional peak power density (216.7 mW cm-2) and specific capacity (784.4 mAh g-1), with a cycling stability exceeding 1200 hours, among the best values reported to date in the field.
