Price Negotiable
Price: 1-1000USD/Negotiable
MOQ: 100g
Delivery Time: 5-7 days
Brand: XWELL
Product Description
Lithium metal foil (Li foil) serves as a critical anode material for next-generation solid-state batteries, delivering ultra-high theoretical capacity (3,860 mAh/g) and the lowest electrochemical potential (-3.04 V vs. SHE). With customizable thicknesses down to ≤20 μm, this material enables energy densities exceeding 500 Wh/kg while addressing key challenges like dendrite suppression and interfacial stability in solid-state systems.

Material Advantages
Energy Density Enhancement
  • Replaces graphite anodes, increasing capacity by 10× (3,860 vs. 372 mAh/g)
  • Enables 1,000+ Wh/L cell-level energy density in solid-state configurations
Solid-State Compatibility
  • Engineered interfaces with sulfide/oxide electrolytes (e.g., Li₆PS₅Cl, LLZO)
  • Low volume change (<5%) compared to silicon anodes (>300%)
Advanced Manufacturing Capabilities
  • Roll-to-roll (R2R) production at 30 m/min (e.g., ULVAC's EWK-030 system)
  • Thermal evaporation for <17 μm foils with ±1 μm tolerance
Applications
  • Solid-State Batteries: EV powertrains, eVTOL aircraft, medical devices
  • Hybrid Designs: Lithium metal pre-plated on Cu/Si anodes
  • Research & Development: Prototyping high-energy-density cells
