The intrinsic catalytic activity of conventional spinel electrocatalysts hinders their electrocatalytic outcomes in lithium–oxygen batteries (LOBs), despite appeal due to compositional variety and structural adaptability. In this work, we reveal that the activities these catalysts can be inherently enhanced by modulating metal–oxygen (M–O) bond covalency interactions through introduction Cr element into MnCo2O4 octahedral sites (MnCr0.5Co1.5O4). Cr3+ directly alters coordination structure Co sites, which increases Co3+–O distance reduces lattice symmetry, resulting M–O bond. Computational analysis supports effectiveness altering electronic active site, narrowing energy gap between 3d O 2p orbitals, evidencing enhancement covalency. addition, increased accelerates charge transfer oxygen-related reactions, thereby facilitating reversible formation decomposition discharge products LOBs. As a proof concept, MnCr0.5Co1.5O4 catalyzed LOBs exhibit large capacity 16 388.3 mAh g–1 maintain stability over 329 cycles. This work paves way for progression manipulating catalysts.
