Abstract

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.
