Sodium-sulfur (NaS) batteries are a promising energy storage technology for a number of applications, particularly those requiring high-power responses [11,21]. It is composed of a sodium-negative electrode, a sulfur cathode, and a beta-alumina solid electrolyte that produces sodium pentasulfide during the discharge reaction .
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.
Another promising technology, sodium-sulfur batteries (Na-S), aroused widespread interest due to their sizeable theoretical capacity and economic nature.
Sodium sulfur batteries were developed in 1960 by Ford. Later it was sold to a Japanese company NGK. The batteries operate at very high temperatures between 300 and 350˚C. In a sodium sulfide battery, molten sulfur is used as the cathode and molten sodium is used as the anode.
Our standardized photovoltaic power generation and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
