Intermediate honeycomb ordering to trigger oxygen redox chemistry in layered battery electrode
Open accessAbstract
Sodium-ion batteries are attractive energy storage media owing to the abundance of sodium, but the low capacities of available cathode materials make them impractical. Sodium-excess metal oxides Na 2 MO 3 (M: transition metal) are appealing cathode materials that may realize large capacities through additional oxygen redox reaction. However, the general strategies for enhancing the capacity of Na 2 MO 3 are poorly established. Here using two polymorphs of Na 2 RuO 3, we demonstrate the critical role of honeycomb-type cation ordering in Na 2 MO 3. Ordered Na 2 RuO 3 with honeycomb-ordered [Na 1/3 Ru 2/3]O 2 slabs delivers a capacity of 180 mAh g−1 (1.3-electron reaction), whereas disordered Na 2 RuO 3 only delivers 135 mAh g−1 (1.0-electron reaction). We clarify that the large extra capacity of ordered Na 2 RuO 3 is enabled by a spontaneously ordered intermediate Na 1 RuO 3 phase with ilmenite O1 structure, which induces frontier orbital reorganization to trigger the oxygen redox reaction, unveiling a general requisite for the stable oxygen redox reaction in high-capacity Na 2 MO 3 cathodes.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
