OCSiAl, a leading producer of single-wall carbon nanotubes, and Green Energy Origin (GEO), a new energy integrated raw materials innovation technology platform, have signed a long-term manufacturing agreement. This partnership focuses on producing TUBALL™ BATT graphene nanotube suspensions in the Czech Republic to enhance the performance of cathodes in lithium-ion batteries. The strategic collaboration aims to improve the effectiveness, resilience, and sustainability of the European battery supply chain.
With a planned annual production capacity of 10,000 metric tons of nanotube suspension, this initiative is sufficient to enhance the cathodes of up to 5 million electric vehicles equipped with typical 65–70 kWh battery packs. The product has already gained market acceptance and is in high demand among producers of EV batteries with thick LFP and NCM cathodes, as well as those utilizing advanced battery technologies, including high-nickel low-cobalt cathode materials and single-crystalline NCM cathodes.
The nanotube suspension enables the maximization of energy density by increasing the active material content up to 98.8%, thanks to a 10–60 times lower loading of conductive additive compared to standard solutions. It also boosts discharge power, enhances safety by reducing battery resistance (DCR), and improves cohesion between cathode material particles by creating a robust network of graphene nanotubes that bond the particles together.
“Looking forward, our partnership will prioritize sourcing raw materials for batteries, enabling critical applications in electric mobility, energy storage, and robotics, all in pursuit of a more sustainable future. Together with OCSiAl, we are dedicated to achieving technical advancements, lowering carbon emissions, and refining manufacturing processes to drive a fully electric, sustainable future. We are excited to embark on this promising journey with such a respected company,” stated Martin Saewe, President of GEO Europe.
“OCSiAl has selected GEO for its OEM production in Europe due to their experience with cutting-edge technologies and established highly efficient manufacturing processes. The production processes will be designed and carried out in accordance with IATF 16949 and VDA 6.3 standards, tailored to meet the high demands of the automotive industry. The site will also be regularly audited by OCSiAl and its automotive clients,” said Konstantin Notman, CEO of OCSiAl Group.
Tony Ma, CEO of GEO, remarked, “This is a good start, and I am optimistic that our two companies will achieve even greater success together, contributing to a greener and cleaner planet. I have full confidence in this long-term partnership, as we share aligned values, strategic goals, a collaborative spirit, and robust supply chain capabilities.”
This new partnership enhances OCSiAl’s leadership in the global new energy materials market. The company has licensed production partners Shanghai Haiyi and Shenyang Huijing for graphene nanotube-based suspensions in China for anodes and cathodes and has recently launched in-house manufacturing of nanotube dispersions for high-performance anode applications, including silicon-rich anodes and fast-charging graphite in Europe.
