Herein, we report a room-temperature sodium–sulfur battery with high electrochemical performances and enhanced safety by employing a “cocktail optimized” electrolyte system, containing propylene carbonate and fluoroethylene carbonate as co-solvents, highly concentrated sodium salt, and indium triiodide as an additive.
Depending on the rate of discharge an efficiency of about 75% was achieved. Self-discharge amounted to about 20% per day. Because the development of sodium–sulfur batteries for mobile applications has effectively ceased, only stationary applications will be discussed below.
The theoretical cell voltage amounts to 2.076 V. The following cell reactions take place: Advantages of the sodium–sulfur battery are their high coulombic efficiency, the use of low-cost materials, and their high expected cycle life.
There are programmes underway to develop lower temperature sodium sulfur batteries. This type of cell has been used for energy storage in renewable applications. The largest installation to date is a 34 MW, 245 MWh facility in Japan that is used for grid support to provide wind energy stabilization.
