Question: Which institute has developed Iron Ion battery system in place of Lithium ion battery?
(a) IIT Madras
(b) IIT Bombay
(c) IIT Hyderabad
(d) IIT Delhi
Answer: (a)
Related Fact:
- Indian Institute of Technology (IIT), Madras researchers have for the first time fabricated a rechargeable iron ion battery using mild steel as the anode.
- The iron ion battery is cost-effective and the amount of energy that can be stored in the battery is also high. While lithium ions are the charge carriers in lithium ion battery, the Fe2+ ions perform that function in the case of iron ion battery.
- With the world turning its attention to electric vehicles, the focus is on developing batteries that are cheaper.
- With no lithium reserves in India and shortage of lithium reserves in the world, the stress is on developing rechargeable batteries of comparable performance using materials other than lithium.
Lithium-ion battery:
- A lithium-ion battery or Li-ion battery (abbreviated as LIB) is a type of rechargeable battery.
- Lithium-ion batteries are commonly used for portable electronics and electric vehicles and are growing in popularity for military and aerospace applications.
