Among the many materials you can find in Subnautica, lithium is one of the more common raw materials, yet you will need lots of it throughout the game. Some important late-game recipes require lithium, such as the plasteel recipe that calls for both lithium and titanium. Luckily, it\u2019s pretty abundant, but you got to know where to look for it. This guide will explain how and where to get lithium in Subnautica. Related: How to get diamonds in Subnautica Where to find lithium in Subnautica There are three ways to find lithium in the game. You can find it on the seabed, by mining shale outcrops, or in large resource deposits. Some biomes are better than others, but you should keep an eye out for lithium in: Blood Kelp Zone Blood Kelp Caves Bone Fields Bone Fields Caves Bulb Zone Bulb Zone Caves Crag Field Crash Zone Mesas Deep Sparse Reef Dunes Grand Reef Grand Reef Caves Inactive Lava Zone Inactive Lava Zone Corridor Jellyshroom Caves Lost River Corridor Ghost Forest Junction Mountain Island Mountains Mountains Caves Mountains Corridor Mushroom Forest Mushroom Forest Caves Sea Treader's Path Sea Treader's Tunnel Caves Sparse Reef Underwater Islands Underwater Islands Caves For best results, we recommend that you farm lithium by looking for large resource deposits, especially in the general\u00a0Lost River\u00a0biome and\u00a0Mountains\u00a0and\u00a0Mountain Island Caves. How and where to get lithium in Subnautica: Below Zero Similarly, in Below Zero, you should look for lithium within ore veins on the seabed, or alternatively, you can get it from Sea Monkeys. All biomes that contain lithium are: Arctic Spires Crystal Caves Main Crystal Caves Deep Purple Vents Deep Twisty Bridges East Arctic Purple Vents Thermal Spires Tree Spires Tree Spires Fissure The best areas in Below Zero to look for lithium are\u00a0Purple Vents. Alternatively,\u00a0Arctic Spires\u00a0have lots of ore veins, so drilling for lithium (and other ores) there can be very profitable.
