Lithium (Subnautica)

Lithium is a raw material found in many biomes. Lithium appears on the seabed, in shale outcrops, and sometimes out in the open.

It can be found as a large resource deposit, they are especially plentiful in the Lost River, Mountains, and the Mountain Island's caves.

Its main use is to create the high strength Lithium/Titanium alloy known as plasteel.
