Abstract
β"-alumina has been shown to have superior sodium conduction compared with β-alumina, and therefore is used as the electrolyte material in sodium battery systems. The β"-alumina structure is composed of layers of (111) oriented spinel-structure units separated by conduction planes that are comparably more open allowing for sodium diffusion. The β-alumina structure is similar except that the spinel units are aligned differently creating a smaller and less flexible conduction plane. In addition to being more flexible, β"-alumina is able to absorb stabilizing ions into the spinel unit, whereas β-alumina does not appear to have that capability. In this paper we analyze the differences in these structures that affect sodium conduction. This comparison will assist in understanding the β"-alumina structure and enhancing its capacity for greater conduction of sodium.
