Technical FAQs 4

What is a sodium sulfur battery?

The as-developed sodium–sulfur batteries deliver high capacity and long cycling stability. To date, batteries based on alkali metal-ion intercalating cathode and anode materials, such as lithium-ion batteries, have been widely used in modern society from portable electronics to electric vehicles 1.

Why are sodium-sulfur batteries a problem?

Sodium–sulfur batteries face significant challenges due to the high solubility of sodium polysulfides and the resulting shuttle effect, which compromise cycling stability and efficiency. This study...

What are the advantages of molten sodium-sulfur (Na-s) battery?

For grid storage, the molten sodium-sulfur (Na-S) battery holds many advantages including the high natural abundance of sulfur and sodium for low-cost and higher energy density (theoretical specific energy density of 760 W h/kg) when compared to vanadium redox flow and lead-acid batteries , .

Are sodium–metal batteries sustainable?

Sodium–metal batteries (SMBs) are an appealing sustainable low-cost alternative to lithium–metal batteries due to their high theoretical capacity (1165 mA h g −1) and abundance of sodium. However, the practical viability of SMBs is challenged by a non-uniform deposition and uncontrollable growth of dendrites at the Na–metal anode.
