The sluggish kinetics and mutual interference of oxygen evolution and reduction reactions in the air electrode resulted in large charge/discharge overpotential and low energy efficiency of Zn‐air batteries. In this work, we designed a breathing air‐electrode configuration in the battery using P‐type Ca3Co4O9 and N‐type CaMnO3 as charge and discharge thermoelectrocatalysts, respectively. The Seebeck...
