Facts
Interesting Facts
  • Heat capacity of Lithium is very high.
  • Lithium inflammable and highly explosive metal, hence it has to be stored properly.
  
  • The main source of Cobalt is as a by-product of copper and nickel metal mining.
  • Cobalt metal can be obtained from other elements like Oxygen, Sulfur and Arsenic.
  • It s also used in electroplating process as it exhibits anti cession properties.

Uses
Uses & Benefits
  • The main usage of Lithium is manufacturing rechargeable batteries for electronic equipment and gadgets.
  • it is also used in manufacturing non-rechargeable batteries.
  
  • Its alloys with aluminum and nickel are used to make powerful magnets.
  • Few other alloys exhibit high-temperature strength and hence they are used in Turbines of Jet and Gas engine.
