Summary: Developing inexpensive and efficient bifunctional oxygen catalysts is crucial for zinc-air batteries (ZABs). A composite of Co, N co-doped carbon nanosheets coupled with NiCo2O4 (NiCo2O4/CoNC-NS) has been developed as an oxygen catalyst, demonstrating good bifunctional oxygen catalytic activity and durability. The assembled liquid ZABs based on NiCo2O4/CoNC-NS exhibit high open circuit potential, peak power density, and large specific capacity, while the solid ZABs also demonstrate high potential, good power density, and superior stability. This work provides a valuable reference for the development of advanced oxygen catalysts in the future.
