Q. Which of the following is/are the advantage/s of Sodium-Ion Batteries?
1.Sodium-Ion Batteries are cheaper than Lithium-ion batteries.
2.Offer better performance in narrow temperature range.
3.Sodium-Ion batteries are non-Inflammable.
Select the correct answer using the codes given below;
The advantages of sodium-ion batteries are,
Abundant Availability: Sodium is the seventh most abundant element in the world and in comparison to lithium, it is available 1200 times more.
Cheaper: Affordable Sodium’s abundance makes this material much cheaper than lithium. The element costs less to extract and purify compared to lithium. Sodium-ion battery cells can be manufactured with ample metals such as iron and manganese.
Note: Lithium-ion batteries require cobalt, which is limited in reserve and distributed across the world in an uneven manner.
Better Performance at Colder Temperatures: Sodium-ion batteries offer better performance and can operate at a wider temperature range. They work much more efficiently in cold environments, compared to lithium-ion batteries.
Non-Inflammable: Another advantage of sodium-ion batteries over lithium-ion batteries is they are nonflammable and there is no thermal runaway. This means the risk of the battery catching fire is less.
Can be Easily discharged: Sodium-ion batteries can be totally discharged to zero volts, similar to a capacitor, making it a safer option in comparison to many other storage technologies.
Lightweight: Sodium-ion batteries are lightweight compared to lithium-ion batteries.
Simple disposal strategies: The simple disposal strategies of Na-ion-based batteries can help in addressing the climate mitigation issue.
