A universal strategy for fabricating bimetallic nanoparticle/N-doped carbon electrocatalysts enabling wide-temperature zinc–air batteries

. When integrated into ZABs, FeCo NPs/NC-based batteries demonstrate remarkable peak specific capacity, power density, and cycling stability (800 h). The batteries retain 97.6% and 95.8% of their room-temperature specific capacity at -20 °C and 60 °C, respectively, and exhibit excellent performance across a wide temperature range. This work highlights the potential of BM NPs/NC for practical applications in extreme environments.
