Q. Consider the following statements regarding “Lithium”:
1. It has the lowest density of all metals.
2. It is used in rechargeable batteries for mobile phones, laptops, digital cameras and electric vehicles.
3. Lithium is abundantly available in India.
Which of the statements given above is/are NOT correct?

[A] 1 only

[B] 1 and 2 only

[C] 3 only

[D] 1, 2 and 3

Answer: C
Notes:

Lithium is an alkali metal. It has the lowest density of all metals.  

  • The most important use of lithium is in rechargeable batteries for mobile phones, laptops, digital cameras and electric vehicles.  
  • But as well as the lithium-ion batteries for which it has grown in popularity, the highly reactive and flammable alkali mineral – sometimes referred to as “white gold” – is also used in ceramics and glass, lubricating greases, polymer production, and air treatment.  
  • According to the latest figures from the US Geological Survey (USGS), global lithium production in 2018 reached around 85,000 tonnes – up from 69,000 in the previous year.  
  • Continued exploration efforts have seen global lithium resource estimates reach 62 million tonnes – a significant proportion of which are located in South America’s “lithium triangle” – an area encompassing Chile, Argentina and Bolivia.  
  • India currently imports all its lithium needs.  
  • It imported lithium batteries worth $1.2 billion in fiscal 2019, up from $384 million in FY17.  
  • Recently researchers at the Atomic Minerals Directorate, a unit of India’s Atomic Energy Commission, have estimated lithium reserves of 14,100 tonnes in a patch of land surveyed in Mandya, 100 km from Bengaluru.
