The binder is an inactive component in the electrode sheet of the lithium ion battery, and its main function is to connect the electrode active material, the conductive agent and the electrode current collector, so as to have an overall connectivity between the electrode active material, the conductive agent and the current collector, thereby reducing The impedance of the small electrode.
