Microporous Copper Foil For Battery Lab Researching

Microporous copper foil is a new type of current collector applied to lithium batteries. It is processed on the basis of the original lithium battery copper foil through secondary processing and mechanical drilling, which can maximize the physical and chemical properties of the Copper foil.Our advanced microporous copper foil is engineered to meet the demanding performance requirements of next-generation battery and electronics applications, specifically tailored for different customers. This high-purity, ultra-thin foil features a precisely controlled porous structure, optimizing surface area, conductivity, and mechanical strength for enhanced energy density and cycle life in lithium-ion batteries or flexible electronics.

REACH TO OUR TECHNICAL TEAM

 

 

• Uniform Porosity: Laser/electrochemical etching achieves pore sizes of 5–50 µm with >80% open area, balancing electrolyte permeability and structural integrity.
• Surface Treatment: Proprietary coating enhances adhesion with electrodes while reducing oxidation.
• Thickness Options: Customizable from 6–20 µm (±0.5 µm tolerance) to suit customer specifications.

 

 

Performance Validation:

• Conductivity: <0.5 Ω/sq (meets target).
• Tensile Strength: 250–300 MPa (under optimization for flexibility).
• Thermal Stability: Passed 150°C/24h test with ≤2% deformation.

2. Customer-Specific Tests:

• Compatibility with Korean client's NMC622 cathodes shows promising initial results (95% capacity retention after 100 cycles).
• Pilot-scale adhesion tests ongoing to meet their roll-to-roll processing requirements.

3. Next Steps:

• Finalize pore distribution optimization.
• Submit 50m samples for customer qualification by mid-Q4.

Collaboration: Close feedback loops with the customer ensure alignment on performance targets

3. Can effectively reduce battery internal resistance

4. Can improve electrolyte infiltration in battery cells

5. Can enhance the external adhesion of the foil material

 

 

 

 

Compared with the conventional copper foil, Microporous copper foil more better used for lithium-ion batteries field.Microporous copper foil also is a highly versatile material with a precisely engineered porous structure, offering unique advantages in energy storage, electronics, thermal management, and chemical processes. Key applications fields are:Energy Storage & Batteries(Lithium-Ion Batteries (LIBs) & Beyond, Fuel Cells & Hydrogen Technologies),Electronics & Sensors,Thermal Management,Filtration & Catalysis,Biomedical & Advanced Materials etc.

 

 

 

Q1: What info. should I let you know if i would like to get a quotation for the the Electrolytic copper foil?

A1: The material size (Thickness*Width*Length and total Qty). If possible, it would be more better to advise the application of the product

Then we can recommend the most suitable products with details for confirmation.

 

Q2:How long is your delivery time?

A2:Generally it is 5-10 days base on we have stock on hand. or 15-20 days if no inventory, then need check with our production team for lead time according to the quantity.

 

Q3: Do you provide samples ?

A3:Yes, if standard sizes sample is free but buyer need to pay freight cost.

 

Q4:What is your terms of payment ?

A4: Normal payment term is 30%TT, 70% before shipment get ready to ship

 

Q5: How do you guarantee the quality of the products?

A5: Each step of production and finished products will be carried out inspection by QC department before storing to the warehouse. NG products are not allowed in the completed goods warehouse.
