Lithium ion Battery Conductive Agent

As an important part of the lithium ion battery, the conductive agent, although it occupies a small amount in the battery, it greatly affects the performance of the lithium ion battery, and it plays an important role in improving battery cycle performance, capacity utilization, rate performance and so on.

The primary function of the conductive agent is to improve the electrical conductivity of the electron.In order to ensure that the electrode has a good performance of charge and discharge, a certain amount of conductive agent is usually added during the production of the electrode sheet to collect micro-current between the active substances and between the active substances and the fluid collector, so as to reduce the contact resistance of the electrode and accelerate the movement rate of electrons.

In addition, the conductive agent can also improve the processability of the electrode sheet, promote the infiltration of electrolyte to the electrode sheet, and effectively improve the migration rate of lithium ions in the electrode material, reduce the polarization, so as to improve the charge and discharge efficiency of the electrode and the service life of the lithium battery.

Conducting agents mainly include granular conductive agents such as acetylene black, carbon black, etc., conductive graphite is mostly artificial graphite, fibrous conductive agents such as metal fibers, carbon fiber grown by gas phase method, carbon nanotubes, etc., and new graphene and its mixed conductive paste are used as conductive agents.
