Lithium is one of the most critical crafting materials in Subnautica Below Zero, essential for upgrading your vehicles, base modules, and high-tier survival equipment. Players often find themselves scrambling for this dense metal once mid-game construction begins. Knowing exactly where to look saves valuable time and keeps your oxygen tanks from running dry in dangerous depths.
Top Underwater Biomes for Farming Lithium
The Thermal Spires and Purple Vents biomes are among the earliest and safest places to locate lithium deposits on Planet 4546B. Look along the seabed and rocky cliff faces where loose lithium nodes sit exposed on the ocean floor. Navigating these areas carefully helps you avoid local predators while filling your inventory quickly.
For mid-game exploration, the Deep Lilypads Cave system provides an incredible concentration of large lithium deposits. While navigating these narrow passages requires steady piloting, the abundance of resources makes the trip highly rewarding. Bringing a Seatruck equipped with depth upgrades ensures you can reach these lower caverns safely.
Surface and Terrestrial Mining Locations
Players who prefer staying out of deep water can search the glacial landmasses such as Glacial Basin and Phi Robotics. Lithium deposits line the snowy pathways, ice caves, and frozen cliffsides in these terrestrial sectors. Searching above ground offers a great alternative if your diving equipment is not yet fully upgraded.
Extreme cold poses a constant threat while exploring these icy landmasses, making heat management crucial. Equipping a Cold Suit or carrying plenty of Fever Pepper juice allows for longer surface gathering runs. Collecting lithium from land nodes helps conserve vehicle power while securing steady supplies.
Advanced Gathering Tools and Large Resource Deposits
Unlocking the Prawn Suit with a Drill Arm attachment drastically changes how efficiently you mine lithium. Scattered across deeper biomes like the Crystal Caves are massive lithium formations that cannot be harvested by hand. Using the suit allows you to break down these large veins into dozens of individual pieces in seconds.
Constructing a Scanner Room near mineral-dense zones makes tracking down isolated nodes effortless. Equipping the Scanner Room with HUD chip upgrades highlights every lithium piece directly on your display screen. Combining these detection tools with a heavy mining suit guarantees you never run low on raw materials again.
Essential Recipes Requiring Lithium
Lithium is primarily required for crafting Plasteel Ingot components, which form the structural backbone of advanced underwater bases. Upgrades for the Seatruck, Prawn Suit, and high-capacity oxygen tanks all depend heavily on this durable metal. Securing a steady supply early in your campaign prevents mid-game progression bottlenecks.
Reinforcing your habitat walls with lithium plates prevents flooding as you expand your base deeper underwater. Maintaining high structural integrity becomes increasingly vital as you build complex, multi-story underwater outposts. Stockpiling extra metal in storage containers ensures your future crafting projects proceed smoothly.
