As a new type of carbon material with special structure, carbon nanotubes(CNTs) have excellent mechanical and electrochemical properties and have been attracting attention in various fields.

In the application of lithium batteries, when carbon nanotubes are used as conductive agents, their unique network structure can not only effectively connect more active materials, but also their excellent electrical conductivity can greatly reduce impedance. In addition, carbon nanotubes with a larger aspect ratio have a larger specific surface area. Compared with traditional conductive agents, CNTs only need a small amount of addition to form an efficient three-dimensional high conductive network in the electrode and achieve the improvement of battery energy density.
