Finding lithium in Subnautica 2 is essential for crafting the plasteel ingots you need to get a bigger, better air tank. It’s also a mineral you won’t be able to get for a little while, as it only starts showing up once you reach waters too warm for survival until you get the necessary mutations. However, there is one spot where you can find plenty of it, more than you’ll need for quite some time.
Below, we show you where to find lithium locations in Subnautica 2.
[Ed. note: Before you dive in, be sure to open the character menu and enable all landmark signals. This will make it easier to spot the locations mentioned in this guide.]
Update (May 15): We added a spot where you can obtain lithium before entering warmer waters, so you can upgrade your air tank prior to tackling the first Angel Comb.
Where to find lithium in Subnautica 2
With one exception, lithium shows up in the areas around the Tadpole Pens, roughly 300 meters east of the Lifepod, and you’ll visit a few during part of the main story as you investigate the region. Most of them are near sources of extreme heat, though, so you’ll need the Angel Comb mutation from the area near Wander’s Blackbox to safely explore. You also need the sonic resonator, as lithium’s a beefy mineral that, in our experience, only comes in massive chunks. If you’re exploring in a tadpole vehicle of your own, make sure to keep an eye on your depth. Some lithium deposits are down pretty far, and the unmodified tadpole can only venture 250 meters deep before it starts imploding.
