Lithium is a material that is obtained by refining petalite in the Ore Refining System. Specifically, petalite ore can be mined using the Mine Extractor in 15-16 minutes with level 4 mine software and then refined 7-8 minutes. Alternatively, a petalite earring can be recycled; this will yield a petalite gem, which can then be refined to gain lithium 1-2 minutes. Petalite ore, gems, and earrings have a stack limit of 50; lithium has a limit of 300.
Lithium is used to produce the following items:
