The only commercially available sulfur-containing energy storage system is the Na/S battery, as illustrated in Fig. 10 (Wen et al., 2013), currently developed by Nippon Gaishi Kabushikigaisha (NGK Insulators, LTD). This system consists of liquid sulfur and sodium electrode, separated by a Na+− conducting membrane (Dunn et al., 2011).

What is the heat transfer behavior of sulfur?

The heat transfer behavior of sulfur was studied in two distinct temperature ranges:∼50–200 °C, and 200–600 °C. In the first stage of thermal charging, the tube surface was uniformly heated to 200 °C, and sulfur temperatures were recorded until steady state was achieved.

Why is sulfur important for battery energy storage?

Due to its abundance and favorable properties, sulfur can play an important role in the major scale-up of battery energy storage. The two main applications are as the active material in metal-sulfur systems and as an electrolyte in the form of weak sulfuric acid, e.g., in lead-acid batteries.

What determines heat transfer performance in a sulfurtes system?

Heat transfer performance is inversely proportional to thecharacteristic length for both horizontal and vertical tubes. The more desirable tube orientation in a SulfurTES system depends on the tube and system dimensions.

What happens if sulfur temperature is below 275 °C?

For the sulfur temperatures below 275 °C, theviscosity of sulfur increases with sulfur temperature and decreases the overall heat transfer rate. Therefore, the temperature difference between the wall and the sulfur also increases, reflecting that the thermal response of sulfur is slowing down.

What is the energy equation for the volumetric-average sulfur temperature?

The energy equation for the volumetric-average sulfur temperature can be expressed as: (13)ρ c p V dT S dt ≅ h L, a v g A T w - T S where V is the total sulfur volume, A is the total sulfur surface area, and Tw is the wall temperature, which is 600 °C for the charge condition and 200 °C for the discharge condition.
