Ingevity Corporation secures rights to produce CHASM’s CNT additives for battery applications
Last update on Nov 26, 2025
Ingevity Corporation has signed a license agreement with CHASM Advanced Materials, Inc. for the latter’s carbon nanotube (CNT) production technology. The $1.79 billion market cap company has seen its stock climb 22.36% year-to-date as it expands its materials technology portfolio.
The agreement grants Ingevity rights to manufacture CHASM’s NTeC-E CNT conductive additives for battery applications in North America and select European countries, building on a joint development agreement signed in February 2024.
Advancing integrated supply chains for EV production
The companies stated that CHASM’s CNT technology was validated through testing to be more conductive than other commercial CNT products while delivering superior capacity retention at high C-rates and over extended cycle life in both commercial lithium-ion cathodes and silicon anodes.
The CNT additives are designed to integrate into various battery chemistries including lithium-ion cathode, high-nickel cathode, silicon anode, and solid-state batteries.
