Chirality‑Induced Suppression of Singlet Oxygen in Lithium–Oxygen Batteries with Extended Cycle Life

Caption

  • Chiral cobalt oxide nanosheets (Co3O4 NSs) suppress singlet oxygen (1O2) generation in Li–O2 batteries via the CISS effect.
  • Operando spectroscopy and density functional theory calculations confirm reduced parasitic reactions and enhanced oxygen electrochemistry.
  • This strategy improves energy efficiency and cycle life, offering a path toward stable, high-performance Li–O2 batteries.
