Technical Features of Copper Foil Production
The production process at SK Nexilis involves several sophisticated steps to achieve the desired quality and specifications of copper foil for EV batteries. These steps include raw material preparation, etching, electrolytic plating, slitting, and quality control.
| Stage | Description | Key Considerations |
|---|---|---|
| Raw Material Prep | Purification and preparation of high-purity copper to ensure consistent quality. | Impurity levels, grain size, and surface finish are crucial for subsequent processes. |
| Etching | Removal of surface imperfections to create a smooth and uniform surface for even plating. | Precise control of etching parameters is essential to avoid damaging the copper. |
| Electrolytic Plating | Deposition of a thin layer of copper onto the substrate using an electrolytic bath. | Current density, bath composition, and temperature affect the foil’s thickness and properties. |
| Slitting | Cutting the plated copper into precise widths to meet the specifications of the battery manufacturers. | Blade sharpness, speed, and tension control are critical to avoid defects. |
| Quality Control | Thorough inspection of the foil’s thickness, surface finish, and other properties to ensure it meets quality standards. | Automated optical inspection and electrical testing are employed. |
Types of Copper Foil Used in EV Batteries
Different types of copper foil are employed in EV batteries, each possessing unique properties suited to specific applications. The choice depends on factors like battery chemistry, desired performance, and cost considerations.
| Type of Copper Foil | Thickness (µm) | Properties | Applications | Advantages | Disadvantages |
|---|---|---|---|---|---|
| High-Conductivity | 6-18 | Excellent electrical conductivity, high purity | Cathode current collectors | High energy density, improved battery performance | Higher cost |
| High-Strength | 10-25 | Enhanced mechanical strength, good conductivity | Applications requiring robust performance under stress | Improved battery durability, resistance to deformation | Potentially lower conductivity than high-conductivity foil |
| Ultrathin | <6 | Extremely thin, high surface area, good conductivity | High-energy-density batteries demanding high surface area for enhanced performance | Maximum energy density, improved battery performance | More challenging to produce, potentially higher cost |
| Surface-Modified | Varies | Enhanced adhesion, improved plating uniformity | Batteries requiring specific surface treatments for optimized performance | Enhanced battery performance, improved manufacturing yield | More complex production process |
