Description

ATOMFAIR® LITHIUM COPPER DOUBLE-SIDED LAMINATED FOIL

SYMMETRIC METALLIC ANODE & HIGH-POWER SPECIAL

Product Overview
The ATOMFAIR® Battery Grade Lithium Copper Double-Sided Laminated Foil is an advanced multi-layered composite anode platform engineered exclusively for next-generation lithium-metal cells, heavy-duty energy storage clusters, and high-precision pilot-scale development. By executing an innovative symmetrical cladding configuration that laminates premium reactive metallic lithium uniformly onto both faces of a high-purity copper core current collector substrate, this hybrid architecture ensures perfectly balanced electron transport and ion flux kinetics. Optimized to mitigate double-sided structural stresses, its configuration delivers premium high-temperature safety barriers and enhanced interface adhesion, eliminating cell polarization to secure uncompromised validation data reproducibility.

Key Features & Advantages
  • Homogeneous Material Purity: Formulated via specialized high-vacuum layer cladding to achieve flat, pinhole-free lithium active networks on both sides of the foil core.
  • Enhanced Operational Efficiency: Built with balanced multi-directional ductility and strong symmetrical layer adhesion, allowing smooth automatic cutting, high-tension winding, and pouch cell stacking without structural fracture.
  • Optimized Microstructure: Symmetrical double-sided configuration balances internal cell mechanical stresses during stripping and plating, suppressing lithium dendrite propagation to prevent catastrophic thermal runaway.

APPLICATION SCOPE: High-performance dual-face anodes for electric vehicle (EV) cells, consumer electronic platforms, large-scale residential and commercial grid storage stabilization, and innovative academic battery material innovation projects.
PACKAGING & OPERATION: Dispatched inside airtight, inert-gas-sealed protective containment roll units. Operators must wear full personal protective equipment (PPE) during assembly; dispose of metal materials following strict local regulations.
IMPORTANT NOTICE: This double-sided active metallic composite foil is highly reactive and decomposes instantly upon any exposure to ambient moisture or oxygen. Keep containment rolls tightly integrated and manage exclusively within argon-filled glove box units with ultra-low dew points to completely eliminate phase decay or oxidation hazards before definitive battery validation workflows.

This lithium-copper laminated foil requires strict moisture and oxygen control to prevent degradation and safety hazards. Storage must be in a cool, dry environment away from direct sunlight and sealed from atmospheric exposure.

  • Moisture Sensitivity: Exposure to moisture can cause lithium corrosion and potential thermal runaway.
  • Temperature Limits: Storage at elevated temperatures may accelerate degradation of the lithium layer.
  • Containment Requirement: The foil must remain in its original sealed packaging until use in an inert atmosphere.
  • Handling Precautions: Operators must wear appropriate PPE including insulated gloves and safety goggles.
  • Disposal Protocol: Dispose of waste foil according to local hazardous material regulations for reactive metals.

This procedure outlines the safe unpacking and preparation of lithium-copper laminated foil for battery assembly. All steps must be performed in a dry room or inert atmosphere glovebox.

Required Equipment: Argon-filled glovebox, Ceramic scissors, Antistatic tweezers, Sealed storage container with desiccant

  1. Inspect packaging
    Inspect the outer packaging for any signs of damage or moisture ingress before opening.
  2. Transfer to glovebox
    Transfer the sealed foil package into the glovebox antechamber and purge with inert gas three times.
  3. Open inner packaging
    Open the inner packaging only after the glovebox atmosphere is confirmed dry and oxygen-free.
  4. Cut foil to size
    Cut the foil to the desired dimensions using ceramic scissors to avoid short circuits.
  5. Store unused foil
    Store unused foil immediately in a sealed container with desiccant inside the glovebox.
  6. Dispose of trimmings
    Dispose of any trimmed edges as reactive metal waste in a designated container.
  7. Clean tools
    Clean all tools with isopropyl alcohol after use to remove lithium residues.

How does the double-sided lamination thickness of the ATOMFAIR Battery Grade DS Laminated Li-Cu Foil influence the trade-off between electrical conductivity and cycle life in lithium-ion batteries?

The double-sided lamination ensures uniform performance and improved adhesion, which enhance durability and cycle life. Custom thickness options allow tailoring of electrical conductivity and energy density, though specific quantitative trade-off data is not provided in the product description.

Can the ATOMFAIR Battery Grade DS Laminated Li-Cu Foil be integrated into existing lithium-ion battery manufacturing processes without requiring modifications to the electrolyte or electrode formulation?

The product is designed for standard lithium-ion battery and energy storage applications, featuring high electrical conductivity and thermal stability. It is intended for use with conventional electrolytes and electrode materials, but no specific compatibility data with alternative formulations is provided.

What are the critical storage and handling requirements to maintain the integrity of the ATOMFAIR Battery Grade DS Laminated Li-Cu Foil and prevent safety incidents?

The foil must be handled with appropriate personal protective equipment and stored in a cool, dry environment away from moisture and direct sunlight. These conditions preserve its thermal stability and reduce the risk of thermal runaway, as stated in the product safety information.

This 280mm wide, 50-meter roll of double-sided laminated lithium-copper foil provides high electrical conductivity and excellent thermal stability, making it suitable for high-performance lithium-ion batteries and energy storage systems. The material's environmental sensitivity to moisture and sunlight necessitates controlled storage conditions, and handling requires PPE due to its reactive nature.
