Carbon-coated Aluminum Foil Battery Current Collector Semi-solid Sodium Battery Scientific Research Laboratory Material

Product Overview​

Carbon-coated aluminum foil (CCAF) is a high-performance current collector engineered for semi-solid-state sodium batteries (SSSBs) and next-gen energy storage systems. By integrating a nano-carbon layer (5–20 μm) onto ultra-thin aluminum foil (8–30 μm), it addresses critical challenges of interfacial resistance, sodium dendrite growth, and electrode delamination in SSSBs.

​Key Specifications​

​Parameter​ ​Specification​
​Base Material​ High-purity Al foil (≥99.6%)
​Coating Composition​ Conductive carbon black/graphite + polymer binder
​Coating Thickness​ 1–8 μm (single/double-sided)
​Surface Roughness (Rz)​ ≤3.0 μm (glossy finish)
​Areal Resistance​ <0.5 Ω·cm² (vs. >2 Ω·cm² for bare Al)
​Thermal Stability​ Stable up to 180°C (SSSB processing)

Material Advantages​

  1. ​Semi-Solid-State Battery Optimization​

    • Reduces interfacial impedance by ​​>50%​​ vs. bare Al foil in sulfide/oxide-based SSSBs.
    • Enhances sodium-ion diffusion kinetics (tested at ​​>5 mA/cm²​​ current density).
  2. ​Sodium Battery Performance​

    • Compatible with ​​Na₃V₂(PO₄)₃ (NVP)​​ and ​​hard carbon​​ electrodes.
    • Mitigates Na dendrites via uniform current distribution (demonstrated ​​>500 cycles​​ at 1C).
  3. ​Research-Grade Customization​

    • ​Surface treatments​​: Lithiophilic coatings (e.g., CuO nanoneedles) for hybrid Li/Na systems.
    • ​Thickness variants​​: Sub-8μm Al foil for ultra-high-energy-density prototypes.

Applications​

  • ​Semi-Solid-State Sodium Batteries​​: Lab-scale prototyping of 200+ Wh/kg cells.
  • ​Hybrid Electrodes​​: Dual-ion (Li⁺/Na⁺) battery research.
  • ​Dry Electrode Manufacturing​​: Solvent-free processing for SSSBs.

​Storage​​: Dry environment (<30% RH) at 25°C.
