Description

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.
