    Abstract We constructed a practical Zn–air battery based on a two-electrode system and developed efficient battery configurations to enhance the battery performance. The battery parameters, including the cell components and operating conditions, were investigated to improve the cell performance by maximizing the reactions at the Zn and air electrodes (oxygen reduction reaction and oxygen evolution reaction). The optimized primary Zn–air battery exhibits the highest power density compared to those in other studies. Furthermore, the rechargeable battery shows stable long-term cycling performance. Thus, our investigation and adjustment of the cell components and operating conditions resulted in a high-performance and durable Zn–air battery. Highlights Cell components and operating conditions in primary and rechargeable Zn–air battery are examined. Primary battery exhibits outstanding performance compared to other reports. Rechargeable Zn–air battery also shows high performance and good capacity retention. Graphical abstract [DISPLAY OMISSION]
