OCSiAl has unveiled a new range of TUBALL™ single wall carbon nanotube (SWCNT) products tailored for next-generation battery technologies. The expanded portfolio is designed to meet the growing requirements of electric vehicles (EVs), portable electronics, energy storage systems (ESS), uninterruptible power supplies (UPS), and battery backup units (BBU) that demand ultrafast response times, high power density, and exceptional reliability.
Anodes
- Ultra-long SWCNT dispersions optimized for silicon-rich anode formulations. These dispersions form robust conductive networks at reduced dosages, enhancing electrode conductivity without compromising energy density.
- Dispersions compatible with lithium-carboxymethyl cellulose (Li-CMC) binders for lithium-ion anodes. These formulations improve first-cycle efficiency and boost charge/discharge performance at higher C-rates.
Cathodes
- N-methyl-2-pyrrolidone (NMP)-based ultrafine SWCNT dispersions. These products stabilize the nanotubes effectively within high-energy cathode materials, supporting elevated power output and overall performance.
Solid-State Batteries
- Ready-to-use SWCNT dispersions formulated for solid-state battery chemistries. These additivated dispersions facilitate the integration of nanotubes in emerging solid electrolyte systems, contributing to ionic conductivity and mechanical stability.
To support global demand, OCSiAl is scaling up its SWCNT dispersion production network, leveraging both in-house and partner facilities across Europe and Asia. The company is also expanding its nanotube synthesis capacity: a second synthesis unit coming online in 2026 will double output, and two additional units planned over the following year are expected to quadruple total capacity. An upcoming project in Luxembourg will further enhance OCSiAl’s ability to produce up to 1,000 tonnes of SWCNTs annually. These investments aim to ensure reliable supply chains and accelerate the adoption of advanced nanotube-enhanced battery materials.
