Robust TUBALL™ single wall carbon nanotube networks work like high-speed highways for electrons and make it possible to achieve uniform low internal resistance and improved durability of electrodes.
Replacement of multi wall carbon nanotubes (MWCNT) with TUBALL™ single wall carbon nanotubes in NCM 811 cells results in lowered DCR increase and improved safety. While carbon black provides surface-level connections between active material particles in standard recipes, TUBALL™ nanotubes form long, fine, conductive bundles that bridge particles throughout the electrode volume. This creates a more efficient conductive network than a combination of MWCNTs with carbon black, which is usually limited to surface connections only.
The unique morphology of TUBALL™ SWCNTs enables not only low resistance but also significant improvements in the mechanical properties of electrodes. Thanks to their high aspect ratio and ability to connect electrode particles over long distances, SWCNTs form a robust conductive and mechanical network throughout the electrode structure. This network helps reduce rebound after calendering, improves electrode flexibility, and enhances electrode integrity during processing. As a result, battery manufacture becomes more stable and efficient, supporting improved electrode handling and cell assembly performance.
TUBALL™ BATT NMP is a ready-to-use solution designed for integration into existing battery cathode production processes. It contains a TUBALL™ nanotube dispersion in NMP developed for improved battery safety and higher energy density of cathodes. TUBALL™ BATT is now available in an optimized, more cost-efficient dispersion form.

SWCNTs play a critical role in enabling high-mass-loading cathodes by forming uniformly distributed electron-conduction networks through strong interactions with cellulose elementary fibril (CEF) binders. The CEF–SWCNT architecture suppresses nanotube agglomeration, improves both ionic and electronic transport, and allows OLO cathodes to reach 50 mg cm⁻² loading while maintaining theoretical capacity and delivering up to 445.4 Wh kg⁻¹ cell-level energy density.
Mono-dispersed ultra-long SWCNTs create a continuous conductive and mechanical network that enables binder-free and self-supporting LFP cathodes with high-rate performance at extremely low additive loadings. The SWCNT framework delivers up to 130.2 mAh g⁻¹ at 5C and 90.7 mAh g⁻¹ at 20C, while providing exceptional mechanical strength, low charge-transfer resistance, and stable cycling without conventional binders or current collectors.
SWCNTs enable high-loading SPAN cathodes by forming efficient electron-percolating networks throughout the electrode, allowing high active-material content and maintaining capacity utilization even at increased mass loadings. Combined with PDA coating, the bimodal SWCNT network delivers areal capacities up to 18.40 mAh cm⁻² and supports stable cycling under high loading and lean-electrolyte conditions.
Debundled and mildly oxidized SWCNTs enable dispersant-free NMP slurries, forming a more homogeneous conductive additive/binder network in Ni-rich NCM811 cathodes. The highly conductive SWCNT framework (2384 S cm⁻¹ film conductivity) improves electrode integrity and delivers ~23.3% higher capacity retention after 100 cycles compared with conventional carbon black electrodes.
SWCNTs dispersed in an alcohol-based, dispersant-free system act as both conductive additives and conductive binders, enabling a more sustainable fabrication route for Ni-rich NCM811 cathodes. The SWCNT network enhances electrode flexibility, conductivity, and rate capability, while maintaining ~78% capacity retention after 150 cycles and outperforming conventional carbon black formulations.
