CHASM and Ingevity Forge Alliance to Secure CNT Supply Chain for EV Batteries

In a significant move that strengthens the cooperative efforts between CHASM Advanced Materials, Inc. (CHASM) and Ingevity Corporation, a new license agreement has been signed to enhance the local supply chain of carbon nanotubes (CNT) for electric vehicle (EV) battery production in North America and Europe. This partnership signifies a deeper commitment to developing high-performance battery materials tailored for the rapidly expanding gigafactory ecosystem in these regions.

Licensing Agreement Overview

On November 11, 2025, CHASM announced the licensing deal in which Ingevity will have the rights to utilize CHASM’s patented low-cost and highly scalable CNT production technology. This technology encompasses CHASM’s NTeC®-E CNT conductive additives specifically designed for battery applications. By tapping into this innovative technology, Ingevity aims to revolutionize its manufacturing processes, providing a locally sourced alternative for manufacturers who are keen on securing reliable supply chains while optimizing performance and sustainability.

The arrangement builds upon an earlier joint development agreement (JDA) made between the two companies in February 2024. The license agreement is expected to significantly contribute to the establishment of a secure and efficient supply chain for CNTs, reducing reliance on overseas materials and bolstering domestic manufacturing capabilities.

Advantages of NTeC®-E CNT Technology

The NTeC®-E carbon nanotube technology from CHASM has undergone rigorous validation through Ingevity's battery laboratories and various third-party testing facilities. The results have shown that NTeC®-E CNTs stand out due to their enhanced conductivity compared to alternative commercial CNT products. Moreover, they exhibit superior capacity retention under high charge rates and extended cycle life, which is essential for both lithium-ion cathodes and emerging silicon anodes used in modern batteries.

CHASM’s CNT additives are not only high-purity and high-performance but also align seamlessly with the requirements for various battery chemistry systems, such as high-nickel cathodes and solid-state batteries. This innovative approach provides a cost-effective and domestically sourced option that empowers North American and European manufacturers in achieving their performance goals while ensuring supply chain stability.

Statements from Leadership

David Arthur, the CEO and Co-founder of CHASM, emphasized the importance of this agreement, stating, "This agreement is a major step toward building a reliable, regionally sourced CNT supply for the rapidly growing EV battery industry. Together with Ingevity, we're enabling battery cell producers to achieve performance and sustainability goals without relying on overseas supply."

Ingevity's President and CEO, David Li, echoed these sentiments, recognizing the milestone this partnership represents. He noted, "This milestone marks a significant step in our partnership with CHASM, validating both the strength of their technology and Ingevity's core competencies. We are accelerating our EV battery materials strategy and investing in scalable CNT manufacturing to strengthen our supply chain across North America and Europe."
