The technology

Individualized CNT.
Measurable gains.

Carbon nanotubes arrive tangled with high impurities. Our proprietary process separates them into clean, uniform, high-aspect-ratio strands that disperse more consistently throughout an electrode.

Discuss your formulation →
01

Faster charging

Improved conductivity (Lithium) and crystal control (Pb) for High performance.

02

Higher energy density

More active surface area for greater energy storage.

03

Longer cycle life

Enhanced structural stability for extended battery life.

04

Proven reliability

Engineered for demanding commercial applications.

From nanotube to electrode

Turning carbon nanotubes into a usable performance network.

Carbon nanotubes are exceptionally strong and conductive, but raw CNT naturally arrives as tangled, impure aggregates. Black Diamond Structures separates, purifies, and disperses the tubes so they can form consistent pathways through battery active material.
