Precision Carbons
Tessera Materials produces Hollow Carbon Nano-Onions — a single Precision Carbon platform serving six energy-storage applications simultaneously, from a proprietary process that works across multiple carbon-rich feedstocks.
One Material Class · Six Applications · Multiple Feedstocks
The Material
Tessera Materials' HCNO is a multi-shell hollow carbon structure — each particle smaller than a virus, engineered to atomic-level specification. Unlike flat graphene sheets, graphite particles, or closed-pore scaffolds, the HCNO's concentric shell architecture enables four simultaneous energy-storage mechanisms: intercalation between shells, surface adsorption on the outer shell, internal storage within the hollow core, and void buffering that absorbs electrode swelling without cracking.
The result is a single carbon material that outperforms conventional electrodes in energy density, power delivery, and cycle life — across multiple ion chemistries.
Applications
