NTeC Carbon Nanotube Additives for Batteries and Cement

CHASM Advanced Materials was established in 2015 by carbon nanotube industry veterans Dave Arthur and Bob Praino, and is headquartered in Canton, Massachusetts with an R&D centre in Norman, Oklahoma. It addresses the cost and usability barriers that have limited industrial use of carbon nanotubes (CNTs).

CHASM's patented, low-capex CNT manufacturing platform produces NTeC carbon nanotubes and nanotube hybrids. NTeC-E conductive additives improve power density, cycle life and charge capacity in lithium-ion cathodes, silicon anodes and other chemistries, while NTeC-C additives raise cement strength and allow lower-carbon concrete. The company also offers AgeNT transparent conductive films for heaters and antennas, and licenses its CNT production technology to partners such as Ingevity.

• NTeC-E: high-purity CNT conductive additives for cathodes, high-nickel cathodes, silicon anodes and solid-state cells.
• NTeC-C: CNT cement additive for stronger, lower-carbon concrete using local materials.
• Nanotube hybrids: CNT hybrid materials supplied as dispersions, inks and films.
• AgeNT films: transparent conductive films for ADAS sensor heaters and transparent antennas.
• Scalable reactors: 50 MTA pilot reactor commissioned in 2022 and a 1,500 MTA reactor planned in Norman, Oklahoma.
• Technology licensing: production technology licensed to partners for regional manufacturing.

Cement and ready-mix concrete producers in Vietnam can trial NTeC-C to raise strength and reduce clinker content for green building projects. Battery cell and pack makers can test NTeC-E in cathode and silicon anode formulations. Chemical groups can explore licensing CHASM's CNT production technology for regional supply.

NTeC-E was validated by Ingevity's battery labs, battery OEMs and third-party testers as more conductive than other commercial CNT products, with better capacity retention at high C-rates and over long cycle life. NTeC-C enables low-carbon concrete without imported supplementary cementitious materials and is designed to improve crack resistance. The licensing model lets partners build local CNT supply close to gigafactories.

Carbon nanotubes are becoming a standard conductive additive in lithium-ion batteries, and manufacturers want regional supply chains. Cement makers are also under pressure to cut emissions, as cement accounts for about 8% of global CO2. Southeast Asia's growing battery assembly and construction sectors are potential markets for both applications.

Established 2015; headquartered in Canton, Massachusetts, USA with R&D in Norman, Oklahoma. ISO 9001 certified. License agreement with Ingevity (NYSE) for NTeC-E production in North America and Europe in 2025, following a 2024 joint development agreement. Concrete demonstrations with Terracon and Saudi Readymix (December 2025).
