Lithium is a Alkali metal in group 1. It has a Body centered cubic crystalline structure. This element has two stable isotopes: 6 and 7.

Availability on the Moon

Lithium is available in the lunar regolith[1][2]. Average concentration is low at 10 ppm.

Production and use

Due to the low concentration lithium on the Moon might require extensive installation. 10 ppm is in the range of gold mines on Earth. One million tonnes of regolith would need to be treated to produce 10 tonnes of lithium, making it unpractical as a base resources. The Moon might need to import Lithium.

Lithium is used in energy storage devices and some alloys of aluminum.
