Application of carbon nanotubes material:

Carbon nanotubes are a new type of conductive agent material, which can improve the conductivity of the positive electrode active material better than traditional conductive agents. It is an excellent lithium battery conductive agent. Currently commonly used conductive agents for lithium-ion batteries mainly include carbon black, conductive graphite, carbon nanotubes, carbon nanofibers, and graphene. Carbon black and conductive graphite are traditional conductive agents, which form a point-contact conductive network between active materials; carbon nanotubes, carbon fibers and graphene are new conductive materials, in which carbon nanotubes and carbon fibers are between the active materials A line-contact conductive network is formed, and graphene forms a surface-contact conductive network between active materials. The line contact type and surface contact type can more fully construct the conductive network, which can more obviously improve the activity of the cathode material The conductivity of the material, thereby reducing the amount of conductive agent added to the positive electrode material. Generally speaking, the addition amount of carbon black conductive agent in the cathode material is usually about 3%, while the addition amount of new conductive agents such as carbon nanotubes and graphene can be reduced to about 0.5%~1.0%, which improves the filling of the cathode active material. The amount of energy can help increase the energy density of lithium-ion batteries. Conductive plastics: the same use of the conductive properties of carbon nanotubes, mixed with engineering plastics can be Made of conductive plastic with both conductivity and plastic characteristics, which is widely used in semiconductors and anti-static materials Materials and electromagnetic shielding.
