CHASM Advanced Materials, Inc. announced the signing by Ingevity Corp. (North Charleston, S.C.) of a license agreement for CHASM’s patented, low-cost, and highly scalable carbon nanotube (CNT) production technology. The agreement grants Ingevity the rights to manufacture CHASM’s NTeC®-E CNT conductive additives for battery applications in North America and select European countries.
Building upon the joint development agreement (JDA) signed in February 2024, this new license strengthens the partnership between the two companies and advances their shared mission to build secure, local supply chains for high-performance battery materials supporting the rapidly expanding EV gigafactory ecosystem in North America and Europe.
Under the JDA, CHASM’s NTeC®-E CNT was validated by Ingevity’s battery laboratories, battery OEMs, and third-party testing facilities to be not only more conductive than other commercial CNT products, but also to deliver superior capacity retention at high C-rates and over extended cycle life — in both commercial lithium-ion cathodes and silicon anodes.
CHASM’s NTeC®-E high-purity, high-performance conductive CNT additives are designed to integrate seamlessly into commercial lithium-ion cathode, high-nickel cathode, silicon anode, solid-state, and other emerging battery chemistries, and provide a cost-effective and domestically sourced option for North American and European manufacturers seeking supply chain security and performance consistency.
“This agreement is a major step toward building a reliable, regionally sourced CNT supply for the rapidly growing EV battery industry,” said David Arthur, CEO and Co-founder of CHASM. “Together with Ingevity, we’re enabling battery cell producers to achieve performance and sustainability goals without relying on overseas supply.”
“This milestone marks a significant step in our partnership with CHASM, validating both the strength of their technology and Ingevity’s core competencies,” said David Li, President and CEO of Ingevity. “Building on our over 40 years of expertise in delivering activated carbon-based solutions for the automotive industry, we’re accelerating our EV battery materials strategy and investing in scalable CNT manufacturing to build a stronger, more resilient supply chain across North America and Europe.”
