Due to their properties, carbon nanotubes are genuinely the first universal additive that can be used to improve the performance of materials in various industries: Electrochemical power sources: lithium-ion batteries , Elastomers: tires and other rubber material , Polymer nanocomposite materials , Transparent conductive films .
Nowadays, lithium-ion batteries are the most common portable electrochemical power source due to the optimal combination of their parameters, such as compactness, energy capacity, output power, and cycle life.
The internal mechanism of such batteries is a system of two electrodes, separated by an electrolyte; lithium ion being the charge carrier. 98% of lithium-ion batteries use graphite and its derivatives as the anode, and various lithium compounds as the cathode:
Due to their unique properties, high electrical conductivity and the effect of physical reinforcement, carbon nanotubes modify the cell electrode material and open up an enormous potential to increase its performance and durability.
That is why we do not only develop custom-made solutions, but also invent universal products for the general market.
TUBALL™ BATT suspension is used as an additive to the electrode slurry during the preparation of cathodes for Li-ion batteries with different cathode chemistry. The application of TUBALL™ BATT results in a substantial increase in the Li-ion battery cyclability as well as in an increase in the discharge and charge power.
The main component in TUBALL BATT is the unique TUBALL material. Using high-quality SWCNT when preparing TUBALL BATT allows us to achieve progress in Li-ion battery cyclability, even when adding quantities as low as 0.01% (as a percentage of dry residue) into the electrode material.
TUBALL BATT is supplied in 1, 5, 20, and 200 liters packages and is used in the standard production process through the addition into (or as a complete substitution of) the standard technological solvent at the stage of the preparation of electrode slurry.
We offer water-based and organic-based TUBALL BATT.
Thoroughly dispersed in the electrode paste, TUBALL provides internal electrode reinforcement, improves its mechanical stability during charge/discharge cycles and prevents its cracking and the formation of dead, non-working areas in the electrode during its long-term operation. TUBALL is an excellent electroconductive additive, providing high-quality electrical contact for all particles of active cathode material.
In contrast to multi walled CNT, carbon nanofibers and other similar materials, the TUBALL BATT material does not cause significant changes in electrode slurry viscosity and does not require substantial adjustments in the production process. This is related to the unique properties of the TUBALL material due to the specially designed industrial technology for high-efficient dispersion of SWCNTs in the suspension without significant negative effects on the CNTs' surface and length.
Promising R&D work of the OCSiAl group of companies is focused on developing high-energy and high power anode compositions based on TUBALL and silicon, and using TUBALL in the most common cathode chemistries, such as LCO, NMC (NCM) and others.
