Material Advantages​​

  1. ​​Solid-State Battery Optimization​​

    • Ultra-smooth dual-sided finish (Rz ≤3.0 μm) minimizes interfacial voids with sulfide/oxide solid electrolytes
    • Maintains mechanical integrity at solid-state processing temperatures (180°C tensile strength ≥20 kg/mm²)

  2. ​​Research-Grade Flexibility​​

    • Soft temper design enables >9% elongation for wrinkle-free electrode laminates
    • Compatible with solvent-free dry electrode manufacturing

  3. ​​Customization Options​​

    • ​​Antioxidant treatments​​: Enhanced stability for air-sensitive solid electrolytes
    • ​​Thickness variants​​: Sub-8μm foils available for ultra-high-energy-density prototypes
    • ​​Surface modifications​​: Lithiophilic coatings (CuO nanoneedles, Ag nanoparticles)

Applications​​

  • ​​Solid-State Battery Prototyping​​: Sulfide (Li₆PS₅Cl) and oxide (LLZO) electrolyte integration
  • ​​Lithium Metal Anode Substrates​​: Dendrite suppression via uniform current distribution
  • ​​Flexible Battery Research​​: Foldable/stretchable current collector development

Technical Notes​​

  • ​​Certification​​: Compliant with GB/T standards (test methods per manufacturer specifications)
  • ​​Packaging​​: Vacuum-sealed rolls with desiccant (100m/roll standard)
  • ​​Customization​​: Surface density and antioxidant properties negotiable
