Product Description

Lithium Copper Composite Tape Solid-state Battery Negative Electrode Lithium Foil Material

​Product Overview​​

Lithium-copper (Li-Cu) composite foil is an advanced anode material designed for high-performance solid-state batteries (SSBs). By combining ultra-thin lithium metal (≤20 μm) with a copper current collector, this hybrid structure addresses critical challenges of lithium dendrite growth, interfacial instability, and volume expansion in SSBs. The Cu substrate enhances mechanical strength and current distribution, enabling ​​>500 Wh/kg​​ energy density and ​​>1,000 cycles​​ lifespan.

Material Advantages​​

  1. ​​Dendrite-Free Lithium Deposition​​

    • Copper foil’s lithiophilic surface (e.g., Cu₂S coating) guides uniform Li plating/stripping, eliminating dendrites.
    • Achieves ​​Coulombic efficiency >99.9%​​ in symmetric cells.

  2. ​​Mechanical Robustness​​

    • Cu substrate provides tensile strength (>100 MPa), preventing electrode deformation during cycling.
    • Reduces Li volume change by ​​>80%​​ vs. pure Li foil.

  3. ​​Solid-State Compatibility​​

    • Compatible with ​​Li₆PS₅Cl (sulfide)​​ and ​​LLZO (oxide)​​ solid electrolytes.
    • Low interfacial impedance (<10 Ω·cm²) after 500 cycles.

  4. ​​Manufacturing Scalability​​

    • Roll-to-roll (R2R) production of ​​≤20 μm Li-Cu foils​​ via thermal evaporation or electroplating.
    • Cost: ​​$4.30/m²​​ (projected for gigafactory-scale production).

Applications​​

  • ​​Solid-State Lithium Batteries​​: EV powertrains, aerospace, medical devices.
  • ​​Hybrid Anodes​​: Pre-lithiated Si/C anodes with Li-Cu current collectors.
  • ​​Research​​: Prototyping high-energy-density SSBs.

​​Storage​​: Argon-sealed (<0.1 ppm O₂/H₂O) at 20°C.
