Abstract The design of efficient oxygen reductionreaction (ORR) catalyst with fast kinetics is crucial for high‐performance Zn–air batteries but remains a challenge. Herein, inspired by the oxidative respiratory chain prokaryotes, an ORR electrocatalyst reported mimicking microstructure Staphylococcus aureus and simitaneously utilizing this low‐cost cell as precursor. consists MnO 2 /Co P nanocomposites support on aureus‐derived hollow spherical carbon, which not only accelerates electron transfer improved intrinsic reaction kinetics, also creates OH − concentration gradient enhanced mass efficiency. Such bio‐inspired derived enables rechargeable ultra‐long cycling stability more than 2800 h at high capacity 810.3 mAh g −1 , superior among bio‐derived catalysts. A flexible battery based assembled, it well integrates wireless electronic skin.
