Microporous Copper Aluminum Foil Solid State Battery Lithium Battery

Microporous Copper Foil Aluminum Foil Solid-state Battery Lithium Battery For New Energy Power Battery-grade Current Collector Porous Punching

1. Product Overview​​

Our precision-engineered ​​micro-perforated copper/aluminum foils​​ are designed for next-generation solid-state and lithium-ion batteries. With customizable porosity (up to 40%) and zero burrs, these foils enhance electrolyte infiltration and electrode kinetics while maintaining structural integrity.

​​Key Applications:​​

• Solid-state batteries
• High-energy-density lithium batteries
• Power batteries for EVs/ESS

2. Customizable Specifications​​

Note: Non-standard sizes require mold development.

3. Performance Advantages​​

​​A. Enhanced Electrode Compaction​​

Theoretical thickness reduction due to porosity.

​​B. Superior Rate Performance​​

​​C. Lower Internal Resistance​​

​4. Why Choose Our Foils?​​

Porosity Optimization:​​ Balanced open-area ratio for ionic/electronic conductivity.
​​Process Compatibility:​​ Works with standard rolling pressure (4MPa tested).
Performance Gains:​​ Higher energy density, faster charging, and longer cycle life.

Quality Assurance:​​ Zero burrs, ISO-certified production.

5. Order Information​​
