A Stable Thin‐Film Lithium Electrolyte: Lithium Phosphorus Oxynitride

Yu, Xiaohua, Bates, J. B., Jellison, G. E., Hart, F. X.·1997·Journal of The Electrochemical Society

Abstract

The electrochemical and optical properties of lithium phosphorous oxynitride (Lipon) thin films have been studied with an emphasis on the stability window vs. lithium metal and the behavior of the Li/Lipon interface. Impedance measurements made between −26 and 140°C show that Lipon exhibits a single, Li + ‐ion conducting phase with an average conductivity of 2.3 (±0.7) × 10 −6 S/cm at 25°C and an average activation energy of E a = 0.55 ± 0.02 eV . No detectable reaction or degradation was evident at the Li/Lipon interface, and linear sweep voltammetry measurements on three‐electrode cells indicated that Lipon is stable from 0 to about 5.5 V with respect to a Li + /Li reference. The complex refractive index of Lipon was measured by spectroscopic ellipsometry. Optical bandgaps of 3.45 and 3.75 eV were obtained from the ellipsometry data and from optical absorption measurements, respectively.

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.
