Development of Sodium‐Sulfur Batteries

Abstract

This paper briefly describes sodium sulfur (NAS) battery development with emphasis on the program to establish the technology for the use of a β‐alumina solid electrolyte. Since the mid‐1980s, NGK INSULATORS, LTD. (NGK) and the Tokyo Electric Power Company (TEPCO) have jointly conducted the NAS battery development program in Japan and, in April 2003, NGK launched production on a commercial scale. A critical aspect of NAS battery development has been achieving low resistance to the flow of sodium ions through the β‐alumina solid electrolyte while ensuring material properties consistent with high mechanical strength, as well as with the dimensional stability required for automated manufacturing. The resistance to sodium ion flow within β‐alumina depends on three factors: grain resistivity, grain boundary resistivity, and crystal orientation. NGK's approach to addressing these factors is explained in this paper.

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.
