Activating and Stabilizing Lattice Oxygen in Spinel NiCo2O4 through F, Mn Dual Doping for Rechargeable Zinc–Air Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study exploited the substitution doping of Mn and F in NiCo2O4 to activate and stabilize lattice oxygen, achieving a stable synergistic effect between AEM and LOM to enhance the intrinsic activity of the catalyst. The outstanding bifunctional properties enable its application as an anode catalyst in zinc–air batteries.
