    Battery Copper Foil for Cell Manufacturers | Targray
    Battery grade copper foil is a high-purity (
    >99.9
    %
    ) electrolytic foil used as the essential anode current collector in lithium-ion batteries. It offers high conductivity, flexibility, and is crucial for improving battery energy density and cycling performance. Common thicknesses range from 4.5

    𝜇
    m to 12
    μmu
    𝜇
    m, with 9
    μmu

    m being standard, and it can be customized with carbon coatings for better performance. 
    Key Characteristics and Types 
    • High Purity & Conductivity: Specifically designed to provide low internal resistance and minimize energy loss.
    • Ultra-Thin Options: Available in thin (12–18
      μmu
      𝜇
      m), ultra-thin (6–12
      μmu
      𝜇
      m), and extremely thin ($\sim$4.5–6
      μmu
      𝜇
      m) to increase battery energy density.
    • Carbon-Coated Copper Foil: Conductive carbon coating enhances adhesion to the active material, reduces interface resistance, and prevents corrosion.
    • Meshed/Porous Copper Foil: Designed for high-performance batteries, offering better electrolyte infiltration and higher power density. 
    Common Applications 
    • Lithium-ion Battery Anodes: Acting as the substrate for graphite or silicon coatings.
    • Supercapacitors: Used as a current collector for energy storage devices.
    • Lab Research: High-purity foil is essential for, for instance, Battery Grade Copper Foil for Lab Li-ion Battery Anode. 
    Commonly Available Specifications
