Carbon nanotubes, as one-dimensional nanomaterials, have light weight, perfect hexagonal structure connection, and have many unique mechanical, thermal, optical and electrical properties.

Multi-wall carbon tubes can be used in batteries:

Compared with the widely used graphite materials, carbon nanotubes have their unique application advantages in lithium ion battery anode materials. First of all, the size of carbon nanotubes is at the nanometer level, and the inside of the tube and the interstitial space are also at the nanometer level, so it has the small size effect of nanomaterials, which can effectively increase the reactive space of lithium ions in the chemical power supply; second, carbon nanotubes The specific surface area of ​​the tube is larger, which can increase the reactive site of lithium ions, and as the diameter of the carbon nanotube decreases, it shows a non-chemical equilibrium or a valence of integer coordination number, and the lithium storage capacity increases; third Carbon nanotubes have good conductivity, which increases the free transfer speed of rapid insertion and extraction of lithium ions, and has a very beneficial promotion effect on the high-power charge and discharge of lithium batteries. .
