Recent advances in utilizing 17O isotopic labeling methods for solid-state nuclear magnetic resonance (NMR) investigations of metal oxides for lithium-ion batteries have yielded extensive insights into their structural and dynamic details. Herein, we commence with a brief introduction to recent research on lithium-ion battery oxide materials studied using 17O solid-state NMR spectroscopy. Then we delve into a review of 17O isotopic labeling methods for tagging oxygen sites in both the bulk and surfaces of metal oxides. At last, the unresolved problems and the future research directions for advancing the 17O labeling technique are discussed.
