TUBALL™ BATT H2O efficiently solves the key problem of Si/C anodes, namely poor cycle life.
The ultra-fine and stable dispersion of TUBALL™ SWCNT in TUBALL™ BATT H2O, when added to Si/С anodes during the slurry manufacturing stage (by simply mixing it in), fully covers and electrically connects the anode particles during the charge–discharge process of LIBs, even during the most harsh cycling conditions required by EV manufacturers.
TUBALL™: e-nables the opportunity for LIB manufacturers to use high-energy Si/С anodes with good cycle life in their commercial LIB recipes for the EV market.

ULTRA-FINE TUBALL™ DISPERSION IN H2O
FOR HI-ENERGY SI/C ANODES
IMPROVES CYCLE LIFE OF Si/C ANODES
E-nabling their industrial use in high-energy cells.
The exceptional conductive properties of TUBALL™ SWCNTs allow them to offer the required conductivity, adhesion, safety, rate and cycle performance in cathodes starting from just 0.06% loading, which is “best–in-class”. The typical effective concentration of industrially used MWCNTs or conductive carbon black is 10–50 times higher!
The ultra-low loading level of TUBALL™ SWCNTs allows LIB manufacturers to maximise the energy density of the cathodes by using a higher amount of active material: up to 99% in modern high-energy NCM and other cathode materials.

The unparalleled conductivity of TUBALL™ SWCNTs allows the highest possible energy densities in modern cathode materials to be achieved and also boosts the C-rate performance of LIBs, improving their fast-charge/discharge properties.
