Single-walled carbon nanotubes (SWCNTs) are composed entirely of carbon atoms and can be regarded as one-dimensional materials rolled from a single layer of graphene. Single-walled carbon nanotubes can be used as conductive agents in energy storage devices such as high-energy-density lithium batteries, sodium-ion batteries, and solid-state batteries. They can also be used to develop high-performance nanoelectronic devices, heterojunction photovoltaic devices, nanogas sensing devices, and flexible Electronic devices, etc.[1].
The arc discharge method is the earliest method used to prepare carbon nanotubes. The single-walled carbon nanotubes produced by this method have high purity and good performance.

Product advantages:
High product purity: Compared with low-temperature technology, single-walled carbon nanotubes prepared by arc discharge method have a high degree of graphitization, extremely low structural defects and a single-wall yield of 100%.
Wide application fields: It can be used in the field of energy storage, electronic devices, and photovoltaic devices.
Application advantages:
Arc-processed single-walled carbon nanotubes have been widely used in carbon-based electronic devices, and their performance can greatly exceed that of single-walled carbon nanotubes prepared by low-temperature technology.
As a conductive agent, arc-processed single-walled carbon nanotubes can effectively improve the energy density and rate performance of the battery. Compared with multi-walled carbon nanotubes, the amount added in the battery conductive agent is 10-60 times lower, and it has an effect of up to 2 times the adhesion.
