Single Sided Double Sided Carbon Coated Copper Foil Lithium Sulfur Battery

Single-sided Carbon-coated Copper Foil University Experimental Lithium Battery Current Collector Double-sided Carbon-coated Copper Foil Lithium-sulfur Battery Grade Copper Foil

1. Product Overview​​

Our ​​Carbon-Coated Copper Foil​​ is a ​​high-performance conductive substrate​​ designed for ​​lithium-ion battery anodes​​, particularly for ​​high-energy-density applications​​. With a ​​uniform carbon coating​​ and ​​ultra-high-purity copper base​​, this foil enhances ​​electrode conductivity, adhesion, and cycle stability​​, making it ideal for ​​EV batteries, energy storage, and consumer electronics​​.

​​2. Key Features​​

​​Superior Conductivity​​:

• ​​Surface resistivity <30Ω/25μm²​​ (low impedance for efficient charge transfer).
• ​​Copper purity >99.99%!​​(MISSING) ensures minimal energy loss.
  ​Mechanical Strength​​:
• ​​Tensile strength ≥265MPa​​ and ​​elongation rate ≤6.0%!​​(MISSING) (resists cracking during electrode processing).
  Precision Coating​​:
• ​​Single-side carbon layer (1μm)​​ + ​​total thickness 12±1μm​​ (uniform and controllable).
  Customizable Dimensions​​:
• Standard width: ​​260±1mm​​ (coating width: ​​227±1mm​​).
