Prepping for the Angels: Lithium's Role in Air Tank Upgrades

Subnautica 2: Finding Lithium for Air Tank Upgrades Guide

The moment your air gauge dips into the red, the pressure mounts. You’re facing the deeper, warmer biomes, and the standard air tank simply won't cut it. To survive the challenges ahead and truly tackle the first Angel Comb, you need more than just luck—you need serious firepower, starting with Lithium.

What this means for players: Understanding exactly where to find lithium is the single most critical step before attempting advanced exploration. This mineral is the key to crafting the plasteel ingots necessary for the crucial air tank upgrade.

The Necessity of the Air Tank Upgrade

Lithium isn't just another resource; it is the foundational component for expanding your operational range. The initial air tank limits your depth and duration, creating a significant choke point as the game progresses.

The upgrade itself, which requires plasteel ingots, allows you to withstand the hotter, deeper waters and reach areas previously considered too dangerous or inaccessible. Without this enhanced air tank, progress stalls, trapping you in shallow zones.

To understand the full impact, remember that the ability to safely explore deeper biomes directly impacts your access to rare blueprints and advanced machinery. This isn't just about air; it's about freedom of movement.

Strategic Lithium Locations Guide

Fortunately, recent updates have made acquiring lithium easier, ensuring players can get the resources they need without immediately running into lethal, high-pressure zones. Knowing exactly where to look saves hours of fruitless searching.

When figuring out where to find lithium in Subnautica 2, focus on these three high-yield, accessible zones. These spots were added to minimize the barrier to entry for new players.

Lifepod Vicinity Spots

The most easily accessed spot is located approximately 350 meters south-southwest of the Lifepod. This area is marked by a large wreckage containing a segment of the repair tool blueprint. It’s a great spot to start your initial mineral farming routes.

The Southeast Cave Entrance

For a higher-yield collection, head 550 meters southeast of the Lifepod. This location is also 600 meters southeast of Ruby's Blackbox, making it a useful waypoint for players who are already exploring the central sector. This large cave entrance is a known concentration point for mineral deposits.

Tadpole Pens Cluster

A third, smaller but reliable source is found around the Tadpole Pens, positioned roughly 300 meters east of the Lifepod. This makes it an efficient detour if you are already gathering materials in that quadrant.

Crafting Plasteel Ingots Efficiently

Finding the raw lithium is only half the battle. The next step is converting those raw resources into usable plasteel ingots. This process requires two specific materials: one piece of lithium and one piece of titanium.

You must utilize a processor—a crafting station—to combine these materials. The result is the plasteel ingot, the material needed to construct the upgraded air tank and ensure you can continue your deep-sea journey. Mastering the efficiency of crafting plasteel ingots Subnautica 2 is key to fast progression.

A strong understanding of where to find lithium in Subnautica 2 directly translates to minimizing downtime and maximizing exploration time. Always plan your trips in clusters, gathering lithium and titanium in one outing to complete the upgrade immediately upon return to the Lifepod.

The process is straightforward: Lithium + Titanium $\rightarrow$ Plasteel Ingot. The more ingots you gather, the faster your air tank upgrades will progress, allowing you to tackle the deep-sea mysteries the game has to offer.

As the game introduces more complex biomes, the demand for reliable power and deep-dive capability only increases. Future updates are likely to expand the mineral density in the open ocean, potentially adding entirely new types of conductive metals.

Keep an eye out for new regional deposits near the Pyramid structures; these areas may require a unique combination of minerals to process, pushing players to explore even further.

We anticipate that the next major patch will introduce resource-dependent environmental hazards, requiring specialized mining gear that relies heavily on plasteel, making mineral gathering an even more central mechanic.
