OCSiAl has unveiled a new range of TUBALL™ single wall carbon nanotube (SWCNT) products engineered to meet the performance demands of next-generation batteries. As the market expands beyond electric vehicles and consumer electronics to include energy storage systems (ESS), uninterruptible power supplies (UPS) and battery backup units (BBUs), requirements for ultrafast response, high power density and exceptional reliability have intensified.
Building on over a decade of industrial production and a reputation for high G/D ratio and consistent batch-to-batch quality, OCSiAl’s updated portfolio addresses key electrochemical challenges across anode, cathode and solid-state battery applications.
For anodes, the company offers advanced dispersions incorporating ultralong SWCNTs to form robust conductive networks at lower dosages in silicon-rich formulations. Additional dispersions optimized for lithium-ion systems using lithium carboxymethyl cellulose (Li-CMC) binders are designed to boost first-cycle efficiency and improve charge/discharge rate capability.
On the cathode side, N-methylpyrrolidone (NMP)-based ultrafine dispersions enhance nanotube stabilization, delivering higher power output and overall performance in high-energy cathode materials.
To support emerging solid-state battery chemistries, OCSiAl is also introducing ready-to-use SWCNT dispersions compatible with solid-state electrolytes, facilitating the development of advanced cell architectures.
In anticipation of growing demand, OCSiAl continues to expand its global SWCNT dispersion production network through both partner and in-house facilities in Europe and Asia. This downstream scale-up is complemented by a rapid increase in nanotube synthesis capacity: the second industrial synthesis unit, scheduled for 2026, will double existing capacity, while the third and fourth units, expected online within a year, will raise total output fourfold. Additionally, a forthcoming project in Luxembourg will further bolster global production, targeting a cumulative SWCNT capacity of up to 1,000 tonnes.
These developments position OCSiAl to support advanced cell designs and electrochemical engineering efforts across a diverse range of battery chemistries.
