— Technology / Sulfurlite™The chemistry behind a 300+ Wh/kg cell.
Sulfurlite™ is a production-ready lithium-sulfur platform engineered to remove the weight, safety, and supply-chain constraints that hold today's defense and aerospace platforms back.
— ArchitectureFour pillars.
Lighter by Physics, Not Engineering Tricks.
Sulfur's low atomic mass and high theoretical capacity (1,675 mAh/g vs ~270 for NMC) is the structural reason Sulfurlite™ achieves 400+ Wh/kg at the cell level.
Safer Thermal Envelope.
Our cathode and electrolyte architecture removes the cobalt and nickel oxides that drive Li-ion thermal runaway. Cells stay stable under abuse conditions that destroy NMC.
Sourced Without Conflict Minerals.
Sulfur is abundant, low-cost, and globally available. Sulfurlite™ removes geopolitical exposure baked into cobalt and nickel supply chains.
Engineered for Cycle Life.
A protective electrode structure and proprietary electrolyte formulation address the polysulfide shuttle effect.
— ComparisonSulfurlite™ vs conventional Li-ion.
| Parameter | Li-ion (NMC) | SulfurLite™ |
|---|---|---|
| Specific Energy (cell) | 150–250 Wh/kg | 300+ Wh/kg |
| Cathode chemistry | LiNiMnCoO₂ | Sulfur composite |
| Cobalt content | Required | None |
| Thermal runaway onset | ~150°C | Significantly higher |
| Operating temperature | 0°C / +45°C typical | −40°C / +60°C |
| SULFUR CATHODE | None | 8x cheaper |
| Conflict-mineral exposure | High | None |
| Cost per Wh trajectory | Plateauing | Declining |
