CHASM Advanced Materials has launched NTeC-E conductive CNT additives for Li-ion batteries used in electric vehicles (EVs). Compared with traditional conductive carbon additives used in Li-ion batteries, CNTs enable lower internal resistance, increased energy storage capacity, enhanced rate capability, and longer cycle life.
According to a recent IDTechEx report, the annual demand for CNTs in the Li-ion battery market is projected to reach 50,000 metric tons by 2032, which is about five times greater than the current global CNT production capacity.
CHASM’s new CNT production platform offers a scalable, cost-efficient, and sustainable approach for mass production of high-quality CNTs tailored for Li-ion batteries. The technologies behind this include proprietary (iron-free) catalysts and proprietary (rotary kiln) reactors for CNT synthesis, which are more capital-efficient than traditional fluidized bed reactors used by leading CNT producers.
NTeC-E conductive CNT additives are produced at CHASM’s manufacturing plant in Norman, Oklahoma. CHASM is currently producing its portfolio of NTeC CNT additives products at 50 metric tons and plans to bring online the world’s largest CNT production reactor (1,500 metric tons) during Q4 2024.
CHASM’s NTeC-E conductive CNT additives have been validated by various partners and independent third-party laboratories through rigorous testing. These independent test results have consistently shown that NTeC-E conductive CNT additives perform as well as CNTs made by leading producers in Asia.
Furthermore, test results suggest that NTeC-E conductive CNT additives are compatible not only with multiple cathode types but also with Si-anodes and next-generation solid-state batteries.
In addition, CHASM offers its NTeC-E conductive CNT additives in the form of dispersions (or, conductive pastes) for easy integration with existing battery industry manufacturing processes. Options include aqueous or solvent-based, with or without polymer binders. CHASM’s ability to tailor products for next-generation batteries allows it to meet the evolving needs of the EV battery industry. The company also designs its CNT production processes to minimize waste and reduce environmental impact, ensuring both economic and environmental sustainability.
“As demand for EVs continues to grow, the need for a secure, more capital-efficient, and scalable supply of conductive CNT additives is becoming increasingly important,” said David Arthur, CEO and co-founder of CHASM. “We’re proud to offer a highly scalable and sustainable solution that meets the needs of the global EV battery segment.”
While most CNT suppliers for EV batteries are currently based in Asia, CHASM is positioned to fulfill local supply requirements in the US and Europe. CHASM’s business model includes manufacturing NTeC-E conductive CNT additives and also providing licenses for strategic partners to mass-produce NTeC-E conductive CNT additives themselves.
To accelerate high-volume scale-up and facilitate global CNT production, CHASM seeks to collaborate with EV battery manufacturers and key players in the supply chain.
