Lithium-ion batteries refer to two different types of secondary battery systems that use lithium intercalation compounds that can reversibly intercalate and deintercalation lithium ions as the positive and negative electrodes of the battery. During charging, lithium ions are de-intercalated from the positive electrode and are embedded into the negative electrode through the electrolyte and the separator; when discharged, lithium ions are de-intercalated from the negative electrode and are inserted into the positive electrode through the electrolyte and the separator. The negative electrode of a lithium-ion battery is made by mixing a negative electrode active material, a binder, and an additive, and pasting the paste on both sides of a copper foil, drying and rolling.

Generally, rubber is insulated. If it needs to be conductive, then conductive material needs to be added. Graphite powder has excellent conductivity and lubricating release properties. Processing graphite into graphite powder has excellent lubrication and conductivity. The higher the purity of the graphite powder, the better the conductivity.
