Conductive Coating Technology Overview
Conductive coating is a key innovation in battery electrode substrate treatment. By applying a functional nano-scale carbon layer—comprising conductive graphite and carbon black particles—onto aluminum or copper foil, the surface conductivity of the substrate is significantly enhanced.
Key Advantages:
Provides excellent microcurrent collection from active materials
Reduces contact resistance between electrode material and current collector
Enhances adhesive strength, allowing reduced binder usage
Significantly boosts overall electrochemical performance
Types of Coatings:
Water-Based System: Environmentally friendly and compliant with green production standards
Oil-Based System (Solvent-Based): Offers superior uniformity and coating density in certain applications
