Nano Coated Copper Foil
Nano coated copper foil is a high-performance current collector material engineered to improve battery performance, particularly in fast-charging, high-energy-density, and silicon-based anode systems. By applying a nanoscale conductive or carbon-based coating, manufacturers enhance adhesion, conductivity, and cycling stability.
Description
Product Description
The Nano coated copper foil coating independently developed by HSMetal is customized for fast charging and silicon carbon negative electrode systems. By uniformly coating the copper foil with nano pre coating, the adhesion between the negative electrode coating and the current collector is effectively improved. It is suitable for water-based and oil-based negative electrodes (fast charging graphite, silicon carbon negative electrode, multi-layer coating) and has good basic and processing properties.

Key Features
Nano Pre-Coating Technology
- Uniform carbon coating improves adhesion between the anode material (graphite, silicon-carbon, etc.) and the copper foil current collector.
- Enhances interfacial stability, reducing delamination risks during cycling.
Compatibility with Multiple Anode Systems
- Suitable for both water-based and oil-based anode slurries.
- Optimized for
- Fast-charging graphite anodes
- Silicon-carbon (Si-C) anodes (which suffer from volume expansion issues)
- Multi-layer coating processes
Enhanced Processing & Performance
- Improutes conductivity and mechanical strength.
- Reduces internal resistance, supporting high-rate charging/discharging.
- Maintains structural integrity even with silicon's volume expansion.
