Improved conductivity and reduced risk of battery fires
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.
Mechanical properties
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.

Comparison of Electronic Resistance Measurement Methods and Influencing Parameters for LMFP and High-Nickel NCM Cathodes
SWCNTs (TUBALL) enable the conductive network in high-loading LMFP and Ni-rich NCM cathodes, allowing the study to isolate and quantify contact and compound electronic resistances. The results show that electronic resistance is dominated by contact resistance rather than bulk electrode resistance, highlighting the critical role of SWCNT-based conductive pathways in maintaining electrode conductivity and fast-charge capability

Highly efficient oxidation of single-walled carbon nanotubes in liquid crystalline phase and dispersion for applications in Li-ion batteries
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.
