Mission-Focused. American-Made.
Our proprietary anode material is built for batteries that must survive storage, abuse, and field conditions, not just lab benchmarks.

A Smarter Integration Path
Most advanced anode materials promise more energy, but deliver new problems: swelling, qualification complexity, and manufacturing overhaul. Obsidia takes a different approach, while still providing an energy-density boost. It's designed to make graphite-based lithium-ion batteries tougher, without asking manufacturers to start over.
Obsidia works with graphite, not instead of it. As a graphite-blend additive, it can be evaluated in existing cell designs, lowering qualification risk while improving performance where it matters most.

Built Different. Built to Last.
Low Swelling
Conventional silicon anodes can expand by hundreds of percent during cycling, degrading electrodes and shortening cell life. Obsidia’s coal-derived, silicon-containing carbon architecture is engineered to absorb lithium with minimal volume change.
Stat: ~2–5% reversible volume change in university testing vs. hundreds of percent for typical silicon-rich anodes
Deep-Discharge Tolerance
Obsidia-containing cells have been tested under extreme conditions, including discharge toward ~1.0V, where conventional graphite cells often fail permanently.
Stat: Cells cycled to 1.0V hundreds of times show no capacity degradation and no copper dissolution in their electrolyte
Long-Storage Resilience
For batteries that sit in the field, on a shelf, or in a machine for months before use, Obsidia blends are designed to deliver. When the mission calls, the battery answers.
Stat: 2+ years of fully discharged storage tested without measurable capacity loss
