Conductive carbon coated Aluminium foil for lithium battery cathode electrode

 Products Description 

Conductive Coating for Battery Current Collectors
Overview:
Conductive coating is a breakthrough innovation in the surface treatment of battery conductive substrates. It involves applying a fine, uniform layer of nano-scale conductive graphite and carbon-coated particles onto aluminum or copper foil, creating coated carbon foil/copper foil. This coating significantly improves static electrical conductivity, ensuring efficient microcurrent collection from the active material.

By reducing the contact resistance between the electrode material and the current collector, the conductive coating enhances bonding strength, lowers binder consumption, and ultimately improves the overall electrochemical performance of the battery.

Coating Types:

Water-Based Coating (Aqueous System): Environmentally friendly and compliant with RoHS standards.

Oil-Based Coating (Solvent System): Provides better coating uniformity and is suitable for high-precision applications.
