Microporous Copper Foil
PRODUCT PARAMETERS
Description
Microporous Copper Foil – High-Density Perforated Current Collector for Li-Ion Batteries
Microporous copper foil is a new type of current collector manufactured through secondary processing of conventional lithium battery copper foil. Using precision mechanical processing to create uniform micro-holes, this innovative material maximizes the retention of the original foil’s physical and chemical properties while adding the benefits of a porous structure.
Key Advantages:
- Enhanced Electrolyte Wetting: Microporous structure improves electrolyte penetration and ion transport.
- Reduced Weight: Perforations decrease overall mass without compromising mechanical integrity.
- Improved Electrode Adhesion: Pores provide mechanical interlocking sites for active materials.
- Maintained Material Properties: Secondary processing preserves the excellent conductivity and strength of copper.
- Customizable Designs: Various hole densities and retention patterns available for specific applications.
Applications:
- Lithium-ion battery anodes
- Supercapacitor electrodes
- Lithium-ion capacitors
- Advanced energy storage research
- High-rate battery applications

Structure Modes
1. Full Surface Microporous Foil
- Micro holes across entire width
- No solid side walls
- Maximum porosity and weight reduction
2. Retaining (Ribbed) Microporous Foil
Designed with solid areas (ribs) for enhanced mechanical strength and current collection. Available configurations:
- Both sides blocked
- Both sides + middle ribs
- Multi-wide ribs
Technical Requirement for Ribs:
In ribbed series products, the micro hole density within the rib areas shall be less than 10% of the effective hole density.
