Battery Grade DS Laminated Li-Cu Foil 280mm x 50m ATOMFAIR®

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.

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.

Positive

• Double-sided lamination for uniform adhesion: The double-sided lamination provides uniform performance and improved adhesion, enhancing durability and cycle life in battery assemblies.
• High electrical conductivity and thermal stability: High electrical conductivity ensures efficient energy transfer, while excellent thermal stability allows the foil to withstand high operating temperatures without performance degradation.

Trade-offs

• Sensitive to moisture and sunlight: Storage must be in a cool, dry place away from moisture and direct sunlight to prevent material degradation, as specified in the product safety information.
• Requires PPE during handling: Appropriate personal protective equipment (PPE) must be used during handling due to the reactive nature of lithium-containing materials, adding operational steps and safety protocols.
