The conductive coating is also called pre-coating. In the lithium battery industry, it is usually referred to as a conductive coating on the surface of the positive current collector-aluminum foil. The aluminum foil coated with the conductive coating is called pre-coated aluminum foil or simply coated. Layer aluminum foil, its earliest experiment in the battery can be traced back to the 1970s, and with the development of the new energy industry, especially the development of lithium iron phosphate battery, it has become a hot new technology or new material in the industry.
The conductive coating can effectively improve the adhesion of the pole piece in the lithium battery, reduce the amount of the binder, and also significantly improve the electrical performance of the battery.
