Abstract

Zinc-air batteries are proposed as a promising battery system, although their application may be hindered by oxygen feed requirements. Herein, a zinc-air battery is reported using a functional positive electrode material (CuO). Benefiting from its oxygen reduction catalytic ability and lower redox potential than that of O₂, the battery can switch freely between two modes: Zn-air mode under aerobic conditions with a discharge voltage of 1.28 V and Zn-Cu mode under anaerobic conditions with two discharge voltage plateaus at 1.13 and 0.79 V, breaking the limitation of traditional zinc-air batteries. Significantly, when switching from anaerobic to aerobic conditions, the CuO electrode can be oxidized to the pristine state in approximately 120 s. The analysis of the different characteristics of the electrode material may be enlightening for functional energy storage system design.
