Ingevity gains rights to manufacture CHASM’s NTeC-E CNT conductive additives for batteries in North America
Ingevity Corporation is doubling down on its EV battery ambitions, signing a license agreement with CHASM Advanced Materials to produce the latter’s advanced carbon nanotube (CNT) technology.
The deal positions the $1.79 billion market cap company to expand its materials portfolio amid a 22% stock gain year-to-date.
Under the agreement, Ingevity gains rights to manufacture CHASM’s NTeC-E CNT conductive additives for batteries in North America and select European markets, building on a joint development pact inked in February 2024.
CHASM’s CNTs have been tested to outperform existing commercial products, delivering higher conductivity and stronger capacity retention in lithium-ion cathodes and silicon anodes—even under high C-rates and extended cycling.
“These CNT additives are key to integrating into multiple battery chemistries, from lithium-ion to solid-state,” said David Arthur, CHASM CEO and co-founder. “This agreement is a major step toward building a reliable, regionally sourced CNT supply for the rapidly growing EV battery industry.”
Ingevity CEO David Li added, “We are accelerating our EV battery materials strategy, investing in scalable CNT manufacturing to build a stronger, more resilient supply chain across North America and Europe.”
The partnership is expected to secure local supply chains for the EV gigafactory ecosystem, supporting the industry’s rapid growth.
