OCSiAl

About

OCSiAl Group, founded in 2009 and headquartered in Luxembourg, has achieved the remarkable distinction of becoming the world's largest manufacturer of single-wall carbon nanotubes (SWCNT), enabling mass-market applications through unprecedented production scale and cost reduction. With over $200 million in funding and 500-1,000 employees, OCSiAl operates globally with production facilities in Europe, Asia, and North America, producing its flagship TUBALL SWCNT products measured in tons rather than grams. The company's breakthrough synthesis technology enables continuous, large-scale production of high-quality single-wall carbon nanotubes at costs dramatically lower than previous methods, fundamentally changing the economics of CNT applications. OCSiAl's TUBALL products consist of ultra-long SWCNTs (up to several micrometers in length) with high aspect ratios and excellent electrical conductivity, making them exceptional additives for creating conductive composites, coatings, and energy storage materials. At remarkably low loading levels (typically 0.01-0.1% by weight), TUBALL nanotubes form percolating networks that impart electrical conductivity to polymers, elastomers, and other matrices. The company targets large-volume applications where CNTs can deliver significant performance benefits, including lithium-ion battery electrodes, transparent conductive films, antistatic materials, EMI shielding, rubber compounds, and composite materials. In lithium-ion batteries, TUBALL additives improve electrode conductivity, enabling faster charging, higher power delivery, and better cycle life—critical for electric vehicles and energy storage systems. OCSiAl has established partnerships with major battery manufacturers worldwide, with TUBALL-containing batteries in commercial production for automotive applications. The company has developed application-specific TUBALL formulations including ready-to-use dispersions in various solvents and concentrates optimized for different manufacturing processes, facilitating customer adoption. OCSiAl maintains extensive application development laboratories working with customers to optimize CNT integration into their products and manufacturing processes. The company has achieved regulatory approvals for TUBALL products in multiple jurisdictions, addressing safety and environmental concerns associated with nanomaterials. OCSiAl's remarkable production scale—producing more SWCNTs annually than all other manufacturers combined—has transformed carbon nanotubes from exotic research materials to practical industrial additives. The company's success demonstrates that with appropriate technology and scale, nanomaterials can achieve cost structures compatible with high-volume applications, fulfilling long-standing promises of nanotechnology revolutionizing major industries. As electric vehicles and energy storage demand surge, OCSiAl's position as the dominant SWCNT supplier positions the company at the center of critical technology supply chains.
