Carbon Nanotube Companies

Carbon Nanotube Market

October 2023- South Korea's Kumho Petrochemical Co.and POSCO International Corp. are considering launching a joint venture to produce carbon nanotubes (CNTs), regarded as a next-generation battery material. The two companies also plan to swap their shares worth 300 billion won (USD221 million) to solidify the partnership, people familiar with the matter said on Friday. Kumho is in talks to transfer its CNT technology to POSCO International with an aim to complete the establishment of the JV by early next year, sources said. The partners are also in negotiations on the size of a share swap. As of the end of June, Kumho Petrochemical has 19.5% of its total outstanding shares as treasury stock worth 700 billion won, while POSCO International has a 3.39% stake as treasury stock worth 316 billion won. The two companies are considering a share swap to the tune of some 300 billion won, the sources said.

November 2023- Zeta Energy announced on November 16th that it has demonstrated its graphite-free and cobalt-free lithium-sulfur batteries are on target to reach 450 Wh/kg and over one thousand cycles by the planned commercial launch in 2025. Zeta Energy's batteries are based on a proprietary sulfurized carbon cathode and a lithiated vertically aligned carbon nanotube anode with an industry-standard electrolyte and separator. The batteries do not use graphite, cobalt, or nickel (all of which have been designated critical metals by the World Materials Forum and the S. Department of Energy). Furthermore, because sulfur is widely abundant and economical, the batteries will cost a fraction of the kWh price of today's lithium-ion batteries. They can be produced with a wholly domestic supply chain.

In February 2022, Northern Graphite Corporation signed an agreement to secure 100% interest within Mousseau West Graphics while retaining a 2% royalty.

In April 2020, LG Chem announced the expansion of its business of CNTs Yeosu plant, to increase its capacity to 1200 tons.

In January 2023, Showa Denko KK signed a merger deal with Showa Denko Materials Co. Ltd to establish a unified company called Resonac Holdings Corporation. 

Japan’s Toyo Ink Group colorants and functional materials division, Toyocolor, said in February 2023 that Carbon nanotube (CNT) dispersions of Lioaccum conductive have been selected for the next-gen high-capacity Li-ion batteries by Contemporary Amperex Technology Co., Limited (CATL), the world’s largest battery company.
