Abstract

Highlights

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.

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand. Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields. Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
