Abstract

The electrochemical performance of layered Li-rich oxide Li_1.20Mn_0.54Ni_0.13Co_0.13O₂ (LLO) can be enhanced by a cerium oxide coating (LLO@CeO₂) with tunable interfacial oxygen activity. CeO₂ with oxygen vacancies can suppress the irreversible oxygen release and thus help to restrain structure degradation. This finding presents a strategy to regulate interfacial oxygen activity by coating metal oxides with abundant oxygen vacancies for Li-rich cathodes.
