Q. Which of the following are the advantages of sodium ion batteries over lithium-ion batteries?
These can store more energy per unit weight.
These are less likely to experience thermal runaway.
The element is abundant in nature.
Choose the correct answer using the codes given below: Answer:
1, 2 & 3
Notes:
Sodium ion batteries are cheaper to produce than their lithium counterparts because of the abundance of the raw materials required to make them. The element is abundant in nature—the Earth’s crust has 2.9 per cent of the element while lithium’s share is only 0.01 per cent. Sodium can be found naturally in seawater and also mined from soda ash.
The cost of extracting sodium is at least 20 per cent lower than lithium.
These are energy dense, non-flammable, and operate well in colder temperatures.
These can store more energy per unit weight, this could make them well-suited for larger applications such as electric vehicles.
These are less likely to experience thermal runaway, a condition that can cause fires in lithium-ion batteries.
