Current Collector Foil

When preparing the electrode of lithium ion battery, aluminum foil is used as the cathode current collector foil, while copper foil is used as the anode current collector foil. If a single smooth foil is used, it is recommended to apply the foil on the rough side to increase the bonding force between the current collector foil and the materials. There is no special requirement for the thickness of...

The lithium battery electrode is a coating composed of particles. During the preparation of the electrode, a uniform wet slurry is applied to the metal current collector foil, and then the solvent in the dehumidification coating is removed by drying. Battery binder or dispersant as well as conductive agent such as carbon black are often added to the battery electrode slurry. Although the solid con...
