AI Customer ServiceRoom temperature sodium–sulfur batteries face safety problems caused by the anode sodium dendrites, the insulation problem of the cathode sulfur, the shuttle effect of the intermediate product polysulfide and the loss of active materials caused by its dissolution.
This paper presents a review of the state of technology of sodium-sulfur batteries suitable for application in energy storage requirements such as load leveling; emergency power supplies and uninterruptible power supply. The review focuses on the progress, prospects and challenges of sodium-sulfur batteries operating at high temperature (~ 300 °C).
However, sodium–sulfur batteries have to be kept at high temperatures above 300 °C to keep the reactants liquid, which entails additional effort for heating and thermal insulation, while relatively low round-trip efficiency and further safety concerns over its explosiveness have constrained its wide-scale implementation.
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
The sodium-sulfur battery realizes the conversion between chemical energy and electrical energy through the electrochemical reaction between metallic sodium and elemental sulfur . When discharging, sodium metal produces Na + and electrons. Na + moves with the electrolyte through the separator to the sulfur cathode.
Utility-scale sodium–sulfur batteries are manufactured by only one company, NGK Insulators Limited (Nagoya, Japan), which currently has an annual production capacity of 90 MW . The sodium sulfur battery is a high-temperature battery. It operates at 300°C and utilizes a solid electrolyte, making it unique among the common secondary cells.
