Conductive Nanotubes Composite

  Our Conductive Nanotube Additive is specifically made for improving lithium ion battery cycle performance.  Nanotubes are excellent electrically conductive fibers.  Nanotubes can form conductive networks easily in Lithium Ion battery electrodes which can help to prevent the electrode materials from degradation caused by the expansion and contraction of electrode materials during charging and discharging. Thus, the capacity of battery does not decline with cycling.

Above-Conductive Nanotubes Composite with electrode materials

 

  Carbon Nanotubes are known to be difficult to disperse, due to the bulk nanotubes form which are normally entangled with each other heavily.  Cheap Tubes can now supply our Conductive Nanotubes Composite Additive (CNCA) with our standard MWNTs or our highly conductive graphitized MWNTs (GMWNTs).  We can also supply this in Di Water or NMP solvents.  If we use our functionalized CNCA we do not need to add any surfactants.

          Our Conductive Nanotubes Composite is a Carbon Nanotubes based Conductive Additive for Lithium Ion Battery and other applications.  It is a Nano Composite Material specifically designed for improving Lithium Ion Battery Performance. It is composed of Carbon Nanotubes and of grain electrode conductive additives. By adding grain electrode conductive additives to Carbon Nanotubes, the entangled Nanotubes are well separated. As the result, the Conductive Nanotubes Composite can be dispersed easily in Lithium Ion battery electrode materials. Additionally, due to the synergetic effect between the Carbon Nanotubes and the grain electrode materials, the discharge capacity and cycle life of Li-Ion battery can be improved remarkably. Furthermore, after adding Conductive Nanotubes Composite additive, the tap density of battery electrode coatings can be increased by 10%.

        Using our Conductive Nanotubes Composite Additive, the cycle life of 700mAh053048 Li-ion battery can prolonged one more time, see table 1 details below

Conductive Nanotubes Composite Instructions for Use:

This nanotubes product can be used on anode and cathode of Lithium-Ion batteries with oil or water solvents. When using, dispersing equally the additive in pure solvent (Water or NMP),  then add in binder materials and mix for about 2 hours.  Then add active materials and mix for 4~6 hours. The appropriate quantity of additive is 2~3wt.% on cathode and 1~2wt.% on anode.

This Product is also available in OH or COOH functionalized forms.
