Q. Consider the following statements:
1.Most electric vehicles currently run on Lithium-ion batteries.
2.Nickel- Cadmium(Ni-Cad) batteries are more advanced than Lithium ion batteries as Ni-Cad have a no self-discharge property.
Which of the statements given above is/are correct?
Answer: C
Notes:
Lithium-ion batteries are currently used in most electric vehicles because of their high energy per unit mass relative to other electrical energy storage systems.
Typically, Lithium-ion batteries are smaller and lighter than a NiCad battery. Lithium-ion also two to three times more expensive than NiCad. On the other hand, Lithium-ion has virtually no self-discharge.
