Oxygen's active role could unlock big leaps in battery performance
Researchers at Dundee and Warwick universities have shown that oxygen actively participates in energy storage within lithium‑ion battery cathodes, overturning the view that oxygen is passive. By comparing layered oxide cathodes with phosphates and using advanced modeling and experiments, they demonstrate significant oxygen redox in the charging/discharging process. Published in Nature Nanotechnology, the findings could enable batteries that charge faster, last longer, and are safer for electric vehicles and portable electronics.
