Adv. Energy Mater. 2025, 15, 2403899 DOI: 10.1002/aenm.202403899 In the originally published version of this article, Figure 4d displayed a compressed vertical axis, resulting in a charge–discharge voltage range of ≈1.0–1.8 V. This was inconsistent with Figure 4e–g, which correctly showed the charge–discharge voltage range of ≈1.2–2.0 V. This visual distortion was caused by an unintended aspect ratio adjustment during plotting in Origin and did not reflect any error in the experimental data. The corrected version of Figure 4d, based on the same original dataset, now accurately reflects the intended voltage range. A revised version of the figure has been provided to replace the original. We apologize for this error. Figure 4. a) Polarization and power density curves of Zn-air batteries using Ti4N3Clx/FePc, Ti4N3Ox/FePc, FePc, and 20% Pt/C as cathodic catalysts; b) Specific capacity of Zn-air batteries using Ti4N3Clx/FePc, Ti4N3Ox/FePc, FePc, and 20% Pt/C as cathodic catalysts; c) Photograph of a “BNU” light-emitting diode panel powered by a single Zn-air battery assembled with the Ti4N3Clx/FePc catalyst; d) Galvanostatic charge/discharge cycling performance of rechargeable Zn-air batteries equipped with either Ti4N3Clx/FePc or 20% Pt/C catalysts, at a current density of 15 mA cm−2; e–g) Voltage efficiency of Zn-air batteries utilizing Ti4N3Clx/FePc and 20% Pt/C during different charging and discharging periods.
