With the lowest density of all solid elements, lithium is one of the light metals. The element is a soft alkali metal and has good electrical and thermal conductivity. Lithium shows resistance in dry air. At room temperature, however, it slowly reacts to form lithium nitride. The metal has excellent reactivity and reacts with a large number of elements and compounds (including water). The reactions proceed with the release of heat.
Lithium is widely used in lithium-ion batteries today. These batteries are rechargeable and are used in mobile devices (e.g. smartphones and tablets), laptops and battery tools. Electrically powered vehicles such as e-bikes and e-cars also use these batteries. Lithium is also used as an alloy metal. It can be alloyed with lead, aluminum and magnesium. Lead-lithium alloys are used in railways. Magnesium-lithium alloys are used in aerospace engineering.
