The review focuses on the progress, prospects and challenges of sodium-sulfur batteries operating at high temperature (~ 300 °C). This paper also includes the recent development and progress of room temperature sodium-sulfur batteries. 1. Introduction
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.
Much of the attraction to sodium (Na) batteries as candidates for large-scale energy storage stems from the fact that as the sixth most abundant element in the Earth’s crust and the fourth most abundant element in the ocean, it is an inexpensive and globally accessible commodity.
In the intervening 25 years, Na/S cells have undergone continual development, and the two principal manufacturers of Na/S batteries for electric vehicles, Asea Brown Boveri (ABB) and Chloride Silent Power Limited (CSPL) have made many changes to both cell and battery design to improve safety.
For NaIBs and NaMH batteries, this concern included electrolyte salts, and NaMH also registered concerns over the volatile price of nickel. These concerns not only related to the availability of high-quality chemical manufacturers but also to the regulations for transport and handling of materials.
