-
Lithium Battery Anode Current Collector
The primary application. Ultra-thin (6–15μm) soft annealed copper foil serves as the negative electrode current collector in lithium-ion batteries. -
Electrical & Electronic Components
Flexible printed circuits (FPC), electromagnetic shielding, grounding tapes, and transformer windings. -
Aerospace & Defense
High-reliability conductive paths and shielding in avionics and military equipment. -
New Energy Vehicles (NEV/EV)
Busbars, high-voltage connectors, and battery interconnects. -
Construction & Decoration
Architectural cladding, roofing, and ornamental metalwork.
-
Conduction Path: During charging/discharging, electrons flow through the external circuit to/from the copper foil, which is coated with anode material (typically graphite).
-
Mechanical Support: The copper foil provides a strong yet flexible substrate for the active material, preventing cracking during volume changes.
-
Heat Dissipation: High thermal conductivity (≈400 W/m·K) helps dissipate heat generated during rapid charge/discharge cycles.
-
Corrosion Resistance: The pure copper surface resists electrolyte attack, ensuring long cycle life.
A: Both are high-purity coppers. C11000 (electrolytic tough pitch copper) contains ~0.04% oxygen, while C10200 (oxygen-free) has <0.001% oxygen. For most lithium battery and electronic applications, C11000 offers excellent performance at a lower cost. For welding in reducing atmospheres, C10200 is preferred.
A: Yes, we can produce down to 0.006mm (6μm) for ultra-thin battery foil applications. Please contact our sales team with your specific requirements.
A: The standard MOQ is 1 ton per specification. However, for sample validation or small-batch trials, we may accommodate smaller quantities on a case-by-case basis.
A: All copper foils are vacuum-sealed with anti-tarnish paper and desiccant, then placed in moisture-proof wooden reels or cartons, compliant with standard export packaging.
A: Yes, we can slit coils to your required width (≤600mm) and cut sheets to custom lengths (e.g., 30–1000mm) at no extra charge for large orders.
A: Yes, our C11000 copper foil contains no restricted hazardous substances and is fully RoHS and REACH compliant.
A: Typical lead time is 15–25 days after deposit confirmation, depending on quantity and customization level.
A: Free samples (A4 size or small coil) are available for testing. Buyer typically covers shipping cost.
