Sodium sulfur battery has been adopted in different applications, such as load leveling, emergency power supply and uninterrupted power supply . At this moment, the main obstacles for the large scale applications of sodium sulfur battery is its high production cost which depends greatly on the scale of the battery production.
Since no pumps, valves or exchangers are necessary in the batteries, only field maintenance requirements are limited to periodic inspection and cleaning. Sodium sulfur battery is environmentally benign, since the battery is completely sealed and allows no emissions during operation. More than 99 wt.% of the battery materials can be recycled.
The open circuit voltage of the cell at 350 °C is 2.075 V. Sodium sulfur battery usually works at the temperature raging between 300 and 350 °C, at which sodium and sulfur as well as the reaction product polysulfide exist in liquid state, which affords high reactivity of the electrodes.
Sulfur in high temperature Na-S batteries usually exhibits one discharge plateau with an incomplete reduction product of Na 2 S n (n ≥ 3), which reduces the specific capacity of sulfur (≤ 558 mAh g −1) and the specific energy of battery.

However, the severe shuttling behavior of sodium polysulfides (NaPSs) significantly hinders their commercial visibility. Therefore, several strategies have been …
