Abstract

Monoclinic NaNiO 2 is re-investigated as a positive electrode material for sodium ion batteries. We observe reversible Na extraction and insertion of about 120 mAh/g when NaNiO 2 is cycled between 1.25 V and 3.75 V, though discharge only proceeds to Na 0.91 NiO 2 . The voltage profile shows large and pronounced steps, which are fully reversible. Charging to 4.5 V leads to higher charge and discharge capacity, though with poor coulombic efficiency and rapid capacity fade. X-ray diffraction of charged samples indicates that high voltage charging leads to the formation of an inactive phase.

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.
