In the hybrid spinel Co 2 FeO 4 the Fe 3+ ions can effectively activate the Co 3+ ions through 3d electron delocalization and spin‐state transition. As Z.‐Q. Liu, T. Ma, and co‐workers report in their Communication on page 13291, a bifunctional electrode composed of these Co 2 FeO 4 nanoparticles grown on N‐doped carbon nanotubes is a promising candidate for zinc–air batteries.
