A conductive agent is a key auxiliary material of a lithium battery, which is coated on positive electrode material and negative electrode material. A certain amount of conductive agent will be added during the production of the pole piece to increase the conductivity of electrons and lithium ions.
Factors for choosing a conductive agent: conductivity, amount of addition, and cost. Compared with traditional carbon black, the new conductive agent has the following features: (1) Performance advantages: the lower the impedance, the better the conductivity.
A certain amount of conductive agent will be added during the production of the pole piece to increase the conductivity of electrons and lithium ions. By forming a conductive network on the surface of the active material to speed up the electron transfer rate, it can absorb and maintain the electrolyte at the same time to provide more lithium ions.
The main function of the electric conducting agent is to increase the electrical conductivity between the active materials and/or between the active materials and the current collector. There are five types of conducting agents ranging from carbon black to single-walled carbon nanotubes (SWCNTs).
A type of conductive agent with a one-dimensional structure, due to its fibrous structure, increases the contact with the electrode material particles, greatly improves the conductivity of the electrode, and reduces the pole piece resistance.
Effect of the binder and conductive agent distributions on the electrode properties The adhesion strength increases with increasing number of bonds between the binder and the particles and with increasing number of bonds between the electrode film and the current collector.
