Generally speaking, the amount of new energy battery conductive agent added is 1%-3% of the weight of the positive or negative electrode. The amount of carbon black added to the positive electrode material is usually about 3%, while the amount of carbon nanotube new conductive agent can be reduced to about 0.5%~1%, which increases the filling amount of positive active materials and helps to improve the lithium ion capacity. battery energy density

Compared with traditional carbon black, the addition of carbon nanotubes is about 0.5%-1.5%, which can achieve the effect of enhancing conductivity, which is nearly half of the amount of carbon black. The addition amount is less but the effect is better. This is the main reason why new energy battery companies gradually replace traditional conductive agents with carbon nanotube conductive agents.
