What is lithium

Quick Scoop

Lithium is a chemical element, symbol Li, atomic number 3. It is a soft, silvery-white metal and the lightest metal, with major uses in rechargeable batteries, alloys, glass, ceramics, lubricants, and some medicines.

Core facts

  • Lithium is part of the alkali metals group and is highly reactive.
    • [5][1]
  • It is the least dense metal and can even float on water.
    • [1][5]
  • Its biggest modern use is in rechargeable batteries for phones, laptops, and electric vehicles.
    • [2][9][5]

Where it comes from

Lithium is found in hard rock, especially granitic pegmatites, and also in brines such as salt lakes and geothermal waters. Commercial recovery often comes from spodumene, petalite, lepidolite, or from brine evaporation.

Why it matters now

Lithium remains a major strategic material because battery demand is still driving the market, and recent industry coverage highlights new production permits and investment activity in the lithium sector.

Simple example

If you use a smartphone or drive an electric car, there is a good chance a lithium-ion battery is helping power it. That is why lithium is often discussed as both a chemistry topic and an energy-transition topic.

Bottom line: lithium is a lightweight, reactive metal that is essential to modern batteries and several industrial and medical applications.
