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. Due to the high operating temperature required (usually between 300 and 350 °C), as well as the highly reactive nature of sodium and. ConstructionTypical batteries have a solid membrane between the and , compared with liquid-metal batteries. .
During the discharge phase, sodium at the core serves as the , meaning that the donates electrons to the external circuit. The sodium is separated by a (BASE). .
Pure presents a hazard, because it spontaneously burns in contact with air and moisture, thus safety features are required to avoid direct contact with water and oxidizing atmospheres. Early on th. .
pioneered the in the 1960s to power early-model . In 1989 resumed its work on a Na-S battery powered electric car, which was named . The car had a 100-mile dri. .
NaS batteries can be deployed to support the electric grid, or for stand-alone renewable power applications. Under some market conditions, NaS batteries provide value via energy (charging battery when electr.

What is a reconfigurable topology of a battery?
Literature first proposed the reconfigurable topology of the battery, in which the system reconfiguration could be achieved through five control switches per cell. In the series topology, each battery cell had only two controllable switches, which were used to connect other cells in series or bypass .
Are lithium-ion battery energy storage systems effective?
As increasement of the clean energy capacity, lithium-ion battery energy storage systems (BESS) play a crucial role in addressing the volatility of renewable energy sources. However, the efficient operation of these systems relies on optimized system topology, effective power allocation strategies, and accurate state of charge (SOC) estimation.
What is BS topology?
First, a new type of BS topology is proposed, which can greatly improve the reliability and economy of the system when single or multiple battery cells fail. Compared with the conventional topology, the maximum number of faulty battery cells that the new topology can bear and the economic gains will increase.
How reliable is BS based on a centralized PCs topology?
Assuming that there are four clusters of batteries in parallel, when the centralized PCS topology is adopted, BS is connected to the power grid through a PCS, and the system operating reliability is 0.9986.
While the energy storage capacity of grid batteries is still small compared to the other major form of grid storage, with 200 GW power and 9000 GWh energy storage worldwide as of 2025 according to , the battery market is catching up very fast in terms of power generation capacity as price drops.
