One‐Pot Spray Pyrolysis Fabrication of Multi‐Phase Lithium Manganese Oxide Microsphere Cathodes for Enhanced Lithium‐Ion Battery Performance

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Sr‐LMO microspheres were synthesized by one‐pot spray pyrolysis, forming multi‐phase lithium manganese oxide with Sr‐doped LiMn2O4, Sr2Mn2O5, and Li2MnO3‐like domains. This structure refines particles, suppresses Jahn–Teller distortion, and adds Li+ pathways, delivering superior cycling stability and rate performance over undoped and commercial LMO ...

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.
