[ Sulfurlite™ / Gen II ]
— Battery technology for when failure isn't an option
Power the
unmanned edge.
Valgotech engineers Sulfurlite™ lithium-sulfur cells purpose-built for military drones, long-endurance UAVs, satellites and soldier-worn systems — delivering up to 2× the energy density of conventional Li-ion at a fraction of the weight.
[ Built for mission-critical platforms ]
— MissionEnergy systems for the defense decade.
Modern drones, robotics, and unmanned systems are runtime-bound. Their operators are weight-bound. We build the battery chemistry that breaks both constraints — lighter, safer, and engineered around the realities of the modern battlespace.
— ApplicationsBattery performance that takes mobility farther.
From the warfighter's plate carrier to low Earth orbit, Sulfurlite™ is engineered for the platforms that can't afford to fail.
— TechnologySulfurlite™ — a step-change in energy chemistry.
Our proprietary lithium-sulfur cells replace cobalt and nickel with abundant, low-cost sulfur. The result is a battery that is lighter, safer under thermal stress, and free of conflict minerals — engineered for the platforms that define the next decade of defense and aerospace.
