High Conductivity Glass Electrolytes for Sodium/Sulfur Batteries

摘要

High-soda glasses in the Na sub 2 O-ZrO sub 2 -Al sub 2 O sub 3 -SiO sub 2 system were tested for low resistivity and stability in Na, Na sub 2 S sub 4 , S, and Na sub 2 S sub 3 . The composition that was selected was: 42 (mol%) Na sub 2 O, 8 Al sub 2 O sub 3 , 5 ZrO sub 2 , 45 SiO sub 2 . Effects of tube diameter on specific power and energy were studied. 3 figs.
