Q. Consider the following statements with respect to “Sodium Sulphur Battery”:
1. It is a high-temperature battery which operates at 300°C and utilizes a solid electrolyte.
2. It has a high-power density and is suitable for large-scale energy storage and space applications.
3. It is costlier than lithium battery.
Which of the following codes below given is/are NOT correct?
Answer: D
Notes:
- Sodium Sulphur Battery is a high-temperature battery which operates at 300°C and utilises a solid electrolyte, making it unique among the common secondary cells (rechargeable batteries).
- It has a high-power density and is suitable for large-scale energy storage and space applications. As electrodes are solid are room temperature and therefore inactive when cold and the battery can be stored for more than 50 years in that state.
- The battery must be activated with a heat source and the electrodes become liquid. The biggest advantage of sodium is in the cost area, as it is a far more common material than lithium and is much more widely available. However, the safety concerns greatly inhibit their widespread adoption.
