Increasing Tap Density and Electrode Life in Lithium Ion Batteries

Carbon Nanotubes (CNTs) are one of best electrically conductive nanofibers. They can form conductive networks easily in Li-Ion battery electrodes. Nanotubes can also prevent the destruction of the electrode material caused by the repeated expansion and contraction of the electrode materials during charging and discharging. Thus, the capacity of battery does not decline. The main barrier to utilizing CNTs for Lithium Ion Battery applications is that pure CNTs can't be dispersed easily, because the CNTs are entangled with each other heavily. Conductive Nanotubes Composite (CNTC) from Cheap Tubes is specifically made to address this problem and improve lithium ion battery performance.

Conductive Nanotubes Composite

Cheap Tubes Conductive Nanotubes Composite is composed of CNTs and of grain electric conductive additives. By adding grain conductive additives to CNTs, the entangled CNTs are well separated. As a result the CNTs can be dispersed easily in battery electrode materials. In addition, because of synergetic effect between CNTs and grain materials, the discharge capacity and cycle life of Li-ion battery can be improved remarkably. After adding Conductive Nanotubes Composite Additive, the tap density of battery electrode coatings can increase 10%.

Conductive Nanotubes Composite - Usage Method

Cheap Tubes Conductive Nanotubes Composite product can be used on anode and cathode of Li-ion battery, with the solvents oil or water. When using, disperse equally the additive in pure solvent (water or NMP), then add in binders and mix for about 2 hours, finally add in the active materials and mix for 4-6 hours. The appropriate quantity of additive is 2-3wt.% on cathode and 1-2wt.% on anode.
