Bidirectionally Enhanced Reaction Kinetics in Vanadium Redox Flow Battery via Regulating Mixed‑Valence States in Perovskite Electrodes

Caption

  • A selectively regulating strategy for chemical environments of Mn ion activity donors in LaMnO3 perovskite can bidirectionally enhance vanadium reaction kinetics.
  • The key reactive sites and control steps of perovskite on vanadium redox reactions are established based on electrochemical tests and theoretical calculation.
  • Sr and Ce doped LaMnO3 as anode and cathode catalysts of the vanadium redox flow battery (VRFB) , respectively, synergistically improves the VRFB’s energy storage performance.
