Q. Consider the following statements:
1.Sodium-ion battery has no over-discharge characteristics.
2.Sodium-ion batteries are costlier than Lithium-ion batteries.
3.Sodium-ion batteries have faster charging times and could have a longer lifespan compared to lithium-ion batteries.
Which of the statements given above are correct?

[A] 1 and 2 only

[B] 2 and 3 only

[C] 1 and 3 only

[D] 1, 2 and 3

Answer: C
Notes:

Explanation –

Statement 1 and 3 are correct. Sodium-ion battery has no over-discharge characteristics, which means it can be allowed to discharge to zero volts. Sodium-ion batteries have faster charging times and could have a longer lifespan compared to lithium-ion batteries.

Statement 2 is incorrect. A sodium-ion battery is 20-30 percent cheaper than lithium-ion battery.
