TNCC CNTs Composite Conductive Agent in Lithium Ion Batteries

When carbon nanotubes are used as conductive additives for lithium-ion battery electrode materials, a complete conductive network can be formed in the electrodes with an addition ratio of merely 1% to 2%. Moreover, the formed conductive network will not break due to the expansion and contraction of electrode materials during battery charging and discharging, thereby preventing capacity degradation of commercial lithium-ion batteries caused by damaged conductive networks in service.

After over five years of systematic research, our company has developed carbon nanotube composite conductive additives for lithium-ion batteries. This product fundamentally addresses the dispersion challenge of carbon nanotubes in electrode materials. It also significantly improves the processability of battery electrode sheets, more than doubles the cycle life of lithium-ion batteries, and raises the compaction density of electrode sheets by approximately 10%.
