Product performance

The unique structure of carbon nanotubes determines that they have many special physical and chemical properties.The C=C covalent bond of carbon nanotubes is the most stable chemical bond in nature, so carbon nanotubes have excellent mechanical properties.Theoretical calculations show that carbon nanotubes have great strength and toughness.

Application direction

Application of carbon nanotubes in cathode materials for lithium ion batteries:

1. Carbon nanotubes – silicon matrix composites

Silicon, as the cathode material of lithium battery, has a very high theoretical specific capacity (4200 mAh/g). At the same time, silicon material has a low discharge potential, which is conducive to the output of higher voltage of lithium ion battery, and silicon is abundant. However, in the process of charging and discharging, the volume of silicon changes greatly (about 400%), which makes the silicon material rapidly powder and fail after several cycles, resulting in the cycling stability and rapid change. And silicon doesn't conduct well. The introduction of carbon nanotubes can not only inhibit the volume change of silicon during charging and discharging process. At the same time, the excellent electrical conductivity of carbon nanotubes also helps to improve the transport and diffusion rate of lithium ions in the material, thus improving the lithium storage performance of the composite material.

2.Carbon nanotubes – metal oxide composites

Similar to silicon materials, metal oxides also have the problem of low conductivity and large volume change during charging and discharging. Carbon nanotubes can be compounded with metal oxides on the nanoscale, so as to overcome the disadvantage of poor conductivity of metal oxides and reduce the polarization phenomenon in the charging and discharging process. In addition, carbon nanotubes also provide a mechanical framework for metal oxide particles to avoid capacity degradation due to their pulverization.
