Energy density: The high energy density (110 Wh/kg) and power density (150 W/kg) of sodium sulfur batteries make them ideal for use in various applications. Low-cost materials: As sodium salt is one of the most abundant elements on Earth, sodium sulfur batteries cost less than other batteries, such as lithium-ion batteries.
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.
Safety: As the sodium sulfur batteries operate at very high temperatures, the safety risk makes them less suitable for BTM applications. Moreover, the sodium battery is highly dangerous if the liquid sodium comes into contact with water in the atmosphere. 6. Applications of Sodium Sulfur Batteries
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).
Lifetime is claimed to be 15 year or 4500 cycles and the efficiency is around 85%. Sodium sulfur batteries have one of the fastest response times, with a startup speed of 1 ms. The sodium sulfur battery has a high energy density and long cycle life. There are programmes underway to develop lower temperature sodium sulfur batteries.
The following are the main disadvantages of sodium sulfur batteries: Operational cost: The increased operational cost of sodium sulfur batteries is due to the high temperature (350°C) required to liquefy sodium. Production capacity: Unlike Li-ion batteries, sodium sulfur batteries are not yet established in the market.
