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

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.
Mechanical Robustness
- Cu substrate provides tensile strength (>100 MPa), preventing electrode deformation during cycling.
- Reduces Li volume change by >80% vs. pure Li foil.
Solid-State Compatibility
- Compatible with Li₆PS₅Cl (sulfide) and LLZO (oxide) solid electrolytes.
- Low interfacial impedance (<10 Ω·cm²) after 500 cycles.
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.
