ATOMFAIR® SINGLE-SIDE COATED CARBON COPPER FOIL

RESEARCH GRADE MATERIAL

Product Overview
The ATOMFAIR® Single-Side Coated Carbon Copper Foil is a premium-grade surface-modified current collector engineered for advanced lithium-ion battery anodes, particularly optimized for silicon-carbon (Si/C) anode systems. Featuring a 1µm conductive carbon coating on high-purity electrolytic copper foil (>99.99% purity), this product delivers exceptional interfacial conductivity with surface resistivity <30Ω/25µm2. With 10±1.0µm copper substrate, total thickness of 12±1µm, tensile strength ≥265 MPa, and elongation ≥6.0%, it significantly reduces internal resistance, enhances active material adhesion, and prevents corrosion/oxidation. Competitive coated copper foil pricing makes it ideal for power battery, energy storage Si/C LIB, 3C high-rate Si/C batteries, and aqueous-system lithium-ion battery R&D and production.

Key Features & Advantages
  • Enhanced Electrode Adhesion: The conductive carbon coating increases copper foil surface tension, significantly improving bonding strength between anode active material and current collector, effectively preventing active material shedding and particle detachment during cycling.
  • Superior Energy Density & Cycle Life: Enables reduced binder content in electrode formulation, effectively increasing cell-level energy density while extending battery cycle life through improved interfacial stability and reduced polarization.
  • Anti-Corrosion & Oxidation Protection: The conductive carbon layer acts as a protective barrier, isolating electrolyte and moisture from the copper substrate, effectively preventing copper corrosion and oxidation failure during charge/discharge operations.
  • Ultra-Low Internal Resistance & Polarization: Significantly reduces interfacial contact resistance between copper foil and anode materials, lowering cell internal resistance, minimizing polarization effects, and maximizing active material specific capacity, ideally suited for high-rate charge/discharge conditions.
  • Enhanced Safety Performance: Reduces heat generation during battery charge/discharge cycles, effectively suppressing thermal runaway risks and significantly improving overall cell safety coefficient.
  • Improved Production Yield & Consistency: Uniform and stable physicochemical properties across the product enhance individual cell pass rates and battery pack matching consistency, effectively reducing comprehensive cell production costs.

This graphite coated copper foil must be stored in a cool, dry environment away from moisture and direct sunlight to prevent degradation. Appropriate personal protective equipment is required during handling to avoid contamination and physical injury.

  • Storage Condition: Store the foil in a cool, dry place away from moisture and direct sunlight to maintain material integrity.
  • Handling Requirement: Use appropriate personal protective equipment (PPE) during handling to prevent contamination and physical injury.
  • Disposal Regulation: Dispose of the material according to local regulations for electronic or coated materials.

How does the choice between single-sided and double-sided graphite coating affect electrode performance in lithium-ion batteries?

The double-sided configuration provides graphite coating on both sides of the copper foil, potentially increasing active material loading for higher energy density, while the single-sided option reduces material usage for cost-effective designs. Both configurations maintain the high electrical conductivity and flexibility stated in the product features.

Is this graphite coated copper foil compatible with standard lithium-ion battery electrode fabrication processes?

Yes, the product is explicitly designed for use as an anode sheet in lithium-ion batteries and supercapacitors, making it directly compatible with standard electrode assembly for consumer electronics, electric vehicles, and energy storage systems. Its durable and flexible construction supports integration into both rigid and flexible battery geometries.

What specific storage conditions are required to maintain the integrity of graphite coated copper foil before use?

Store the foil in a cool, dry place away from moisture and direct sunlight to prevent oxidation or degradation of the copper substrate and graphite coating. Additionally, use appropriate personal protective equipment during handling to avoid contamination or physical damage.

This graphite-coated copper foil combines a high-conductivity copper substrate with a conductive graphite coating to improve electrode performance in lithium-ion batteries and supercapacitors, available in customizable thicknesses and single- or double-sided configurations. Storage must be controlled to avoid moisture and sunlight exposure, and handling requires PPE due to potential surface reactivity or particulate hazards.

Positive

  • High electrical conductivity: The copper foil substrate, combined with the graphite coating, provides superior electrical conductivity, enabling efficient energy transfer in battery and supercapacitor electrodes.
  • Customizable thickness options: Available in various thicknesses to match specific electrode design requirements, allowing engineers to optimize active material loading and electrode density.

Trade-offs

  • Moisture and sunlight sensitivity: The product must be stored in a cool, dry place away from moisture and direct sunlight to prevent oxidation or degradation of the graphite coating and copper substrate.
  • Requires PPE during handling: Handling this foil necessitates appropriate personal protective equipment, likely due to sharp edges from cutting or potential graphite particle release during processing.
