The original sodium-sulfur battery separator is β-Al 2 O 3, which can be used as both a solid electrolyte and a separator. However, this sodium-sulfur battery needs to work at a temperature higher than 300 °C. The molten sodium and sulfur may react explosively, and β-Al 2 O 3 cannot prevent the shuttle effect of polysulfides .
