Q. Consider the following statements about Lithium-Sulphur Batteries:
1. It is a type of rechargeable battery with lithium or lithium alloys as cathodic material and sulphur as anodic material.
2. Lithium-ion batteries are commonly used for portable electronics, electric vehicles and in aerospace applications.
Which of the above given statement is/are correct?

[A] 1 only

[B] 2 only

[C] Both 1 and 2

[D] Neither 1 nor 2

Answer: B
Notes:

Statement 1 is incorrect 

  • It is a type of rechargeable battery with lithium or lithium alloys as anodic material and sulphur as cathodic material.
    Advantages: 
  • lower cost of production due to use of sulphur, 
  • capable of storing up to 10 times more energy than lithium-ion ones 
  • energy efficient 
  • improved safety 

Disadvantages: battery physically breaks apart under the stress from repeated charging and discharging of the battery
