Front cover image: Transition metal phosphides are considered highly promising cathode catalysts for zinc-air batteries. However, issues such as phase separation, particle agglomeration, and insufficient active sites during synthesis severely compromise the battery's cycling stability and power density. Interface engineering strategies can effectively mitigate these problems. In article number e70065, a “nanoconfinement phosphorization” strategy was proposed, successfully synthesizing nitrogen-doped carboncoated FeP nanoparticles (FeP–NPC) catalysts. Systematic characterization and theoretical calculations revealed their outstanding bifunctional oxygen electrocatalytic performance. Furthermore, the innovative FeP–N3–C interfacial structure design significantly enhances the long-term cycling stability and power density of zinc-air batteries by regulating the Fe d-band center and optimizing the adsorption energy of reaction intermediates, offering a novel approach for achieving efficient, low-cost metal-air batteries.
