Free-Standing Electrode of Core–Shell-Structured NiO@Co₃S₄ for High-Performance Hybrid Zn–Co/Air Batteries

This work fabricated a free-standing NiO@Co₃S₄ electrode with a core−shell structure. As a result of the high electric conductivity of metal sulfides, synergistic effects between core and shell, a hybrid Zn air battery with this electrode delivers optimal electrochemical performance.
