Lithium is one of several natural resources found within planets in Astroneer. However, unlike most resources, you can only get it on two planets in the game.
Where to get Lithium in Astroneer
To get lithium in Astroneer, you will need to travel to either the planets Vesania or Novus. On these planets you must mine curly pink noodle-shaped nodes. On Vesania, you will need to search cave layers in order to find the resource. But on Novus, you will need to explore mountain biomes and mantle layers instead to find lithium. Alternately, you can trade for this resource with scrap via a trade platform that you can make with the following materials.
- One Tungsten
- One Iron
- One Compound
Once you get lithium, you will be able to make two items: a Medium Battery and an RTG, via a small printer. You can make a small printer with one compound using your backpack module. After this, you can make both items with the resources listed below.
How to make an RTG in Astroneer
An RTG is a power generation item that can supply you with a ton of power, but you will need nanocarbon alloy alongside lithium to make it. You already know how to get lithium, but you will need the following resources inside a chemistry lab to make nanocarbon alloys.
- Titanium Alloy
How to make a Medium Battery in Astroneer
A Medium Battery is a power source in Astroneer, and to make it, you will need both zinc and lithium. Once made, you will be able to use it to power your shuttle.
