Ingevity licenses nanotube production technology for EV batteries

Ingevity (NGVT) signed a license agreement for CHASM’s patented, low-cost, and highly scalable carbon nanotube production technology. The agreement grants Ingevity the rights to manufacture CHASM’s NTeC-E carbon nanotube, or CNT, conductive additives for battery applications in North America and select European countries. CHASM is a U.S.-based carbon nanotube producer enabling global, low-cost, and scalable CNT manufacturing through its technology licensing model. Building upon the joint development agreement signed in February 2024, this new license advances their shared mission to build secure, local supply chains for high-performance battery materials supporting the EV gigafactory ecosystem in North America and Europe.
