Lithium Salts

Lithium salts are gathered by either mining them from the Salt Flats sub biome in the desert, or by building a Lithium Salts Extractor or Advanced Lithium Salts Extractor.

When you go to the Salt Flats, look for the dipped down, light grey/sandy coloured parts and mine the salt clusters. You will receive Salt and Lithium Salt.

On PVE servers, salt extractors can be built on a base in any biome, even outside the Desert.
