Applications:
Carbon NanoTubes-based Conductive Additives for Lithium-ion battery is a composite having high electric conductivity containing carbon
nanotubes and carbon black. It is easily dispersed in Li-ion battery electrodes. Carbon black particles help preventing carbon nanotubes
dispersion from reagglomeration. This product can be used in both anodes and cathodes of the Li-ion batteries. Compared with traditional
conductive additives of Li-ion batteries, the product contributes to the evident superiority of Li-ion batteries as follows:
· Longer cycle life and excellent performance at large currents (increase twice)
· Higher tap density (adding 10%)
· Higher electrode conductivity
· Electrode with higher mechanical strength and adhesive attraction
