2 Facts

2.1 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.

3 Uses

3.1 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.
