Abstract: Room-temperature sodium–sulfur (Na–S) batteries have attracted significant attention for large-scale energy storage due to their high energy density, environmental compatibility, and cost-effectiveness. Nevertheless, their practical application is severely hindered by the shuttle effect resulting from… read more here.
