Structure of sodium–sulfur battery . Sodium β′′-Alumina (beta double-prime alumina) is a fast ion conductor material and is used as a separator in several types of molten salt electrochemical cells. The primary disadvantage is the requirement for thermal management, which is necessary to maintain the ceramic separator and cell seal integrity.
A sodium–sulfur (NaS) battery is a type of molten-salt battery that uses liquid sodium and liquid sulfur electrodes. This type of battery has a similar energy density to lithium-ion batteries, and is fabricated from inexpensive and low-toxicity materials.
... They have a capacity of 4.2mAh/cm 2 and a life of 100 cycles due to reduced oxygen transfer efficiency and the formation of a dense solid electrolyte interphase on the sodium anode. Chawla & Safa conducted a performance review of sodium-sulphur and sodium-air batteries.
In a sodium sulfide battery, molten sulfur is used as the cathode and molten sodium is used as the anode. The electrolyte is a solid ceramic-based electrolyte called sodium alumina. When the battery is discharged each sodium atom gives away one electron forming sodium ions. The electrons take the external circuitry to reach the positive terminal.
Early work on the sodium sulfur battery took place at the Ford Motor Co in the 1960s but modern sodium sulfur technology was developed in Japan by the Tokyo Electric Power Co, in collaboration with NGK insulators and it is these two companies that have commercialized the technology. Typical units have a rated power output of 50 kW and 400 kWh.
Lifetime is claimed to be 15 year or 4500 cycles and the efficiency is around 85%. Sodium sulfur batteries have one of the fastest response times, with a startup speed of 1 ms. The sodium sulfur battery has a high energy density and long cycle life. There are programmes underway to develop lower temperature sodium sulfur batteries.

Progress and Challenges for All-Solid-State Sodium Batteries
The first ASSBs were designed to use a solid-state β-alumina electrolyte for high-temperature (HT) sodium-sulfur batteries in the 1960s. Nevertheless, the severe operation conditions limit their wide applications. Due to efforts over decades, various types of SEs have been developed to meet the requirements of ASSBs at room temperature (RT). Typically, as shown in Figure 1, …
