CoFePx/FeCo@PNCF Nanofibers Featuring PS-Induced Open Channels for Enhanced ORR/OER Performance in Rechargeable Zinc–Air Batteries

), robust initial discharge capability (>300 h), and stability upon cycling (∼563 h, ∼1690 cycles). The solid-state ZABs demonstrate strong performance, and two devices sustain a 2.5 V light-emitting diode (LED) lamp for over 7 days.
