Lithium Ribbon Solid State Battery Negative Electrode Lithium Foil Material

Lithium Ribbon Solid-state Battery Negative Electrode Lithium Foil Material Solid State Battery Materials

Product Overview​​

Lithium metal foil (Li foil) is a critical anode material for next-generation solid-state batteries, offering ultra-high theoretical capacity (3,860 mAh/g) and the lowest electrochemical potential (-3.04 V vs. SHE). With thicknesses customizable 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.

Key Specifications

Material Advantages​​

1. ​​Energy Density Boost​​

   • Replaces graphite anodes, increasing capacity ​​10×​​ (3,860 vs. 372 mAh/g).
   • Enables ​​1,000+ Wh/L​​ cell-level energy density in solid-state configurations.

2. ​​Solid-State Compatibility​​

   • Engineered interfaces with sulfide/oxide electrolytes (e.g., Li₆PS₅Cl, LLZO).
   • Low volume change (<5%) vs. silicon anodes (>300%).

3. ​​Advanced Manufacturing​​

   • 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.
