The $KRKNF “SeaPower" Battery Deep Dive 1. The Tech The core problem in underwater robotics is pressure. At 6,000 meters deep, the ocean exerts over 8,000 psi. To keep batteries from crushing, engineers historically had two bad options: -Option A (Pressure Vessels): Seal standard laptop-style batteries inside a massive, thick titanium tube. However, the tube is dead weight ("The Titanium Tax"). It can account for 30-50% of the vehicle's weight, killing endurance. -Option B (Oil-Filled): Fill a plastic box with batteries and non-conductive oil to equalize the pressure. But oil is heavy, messy, toxic, and makes maintenance a nightmare. The Kraken Solution: Pressure-Tolerant Gel Encapsulation Kraken developed a third way. They take Lithium-Polymer cells and "pot" (encase) them in a proprietary solid-state silicone polymer. The gel is solid enough to hold shape but flexible enough to transfer the ambient water pressure directly to the battery cells (which are solid and don't crush). You delete the heavy titanium tube. You delete the messy oil. The result is a battery system that is ~50% lighter and has significantly higher energy density (more kWh per kg) than the competition. 2. The Competition Kraken is disrupting a field of established defense players. -Southwest Electronic Energy (SWE): The closest direct competitor. Their "SeaSafe" line includes an oil-filled version and a newer "Direct" (potted) version. They are a strong US manufacturer with deep oil & gas roots. Kraken has successfully displaced them on key programs (like Anduril’s Dive-LD) by offering better energy density and a lower price point due to manufacturing efficiencies. -General Atomics (GA): The defense titan. They make the LiFT (Lithium-ion Fault Tolerant) battery. GA focuses on extreme safety for manned submersibles (like the Navy SEALs' dry combat submersible).

Anduril Industries acquired Dive Technologies (maker of the Dive-LD drone). Dive was already using Kraken batteries. Anduril evaluated the market and kept Kraken. As Anduril scales to build hundreds of drones for the Pentagon's "Replicator" initiative, Kraken is the designed-in power source. - The "Black Art" of Potting: It sounds easy to "put batteries in gel," but it is a manufacturing nightmare.

1. The Tech
The core problem in underwater robotics is pressure. At 6,000 meters deep, the ocean exerts over 8,000 psi. To keep batteries from crushing, engineers historically had two bad options:
-Option A (Pressure Vessels): Seal standard laptop-style batteries inside a massive, thick titanium tube. However, the tube is dead weight ("The Titanium Tax"). It can account for 30-50% of the vehicle's weight, killing endurance.
-Option B (Oil-Filled): Fill a plastic box with batteries and non-conductive oil to equalize the pressure. But oil is heavy, messy, toxic, and makes maintenance a nightmare.
The Kraken Solution: Pressure-Tolerant Gel Encapsulation
Kraken developed a third way. They take Lithium-Polymer cells and "pot" (encase) them in a proprietary solid-state silicone polymer. The gel is solid enough to hold shape but flexible enough to transfer the ambient water pressure directly to the battery cells (which are solid and don't crush).
