Abstract

We use in operando Raman spectroscopy to investigate the structural evolution mechanism of transition metal cation and oxygen anion redox in Li-rich layered oxide cathodes. We directly capture the release of oxygen-driven electrolyte oxidation (especially the dimethyl carbonate component) at high-voltage operation (4.4 V).
