Double-Sided Composite Aluminum Foil Current Collector

Product Type: Composite aluminum foil current collector
Research-grade laboratory product

Product Overview

Double-sided composite aluminum foil current collector uses a symmetric three-layer structure with aluminum foil, a 3 μm polymer functional layer and aluminum foil.

The composite foil specification includes mechanical, electrical, electrochemical, electrolyte-stability and thermal-shutdown performance parameters for battery current collector evaluation.

Performance Features
  • Structure is ≥4 μm aluminum foil + 3 μm polymer functional layer + ≥4 μm aluminum foil.
  • Longitudinal tensile strength is specified at ≥165 MPa and longitudinal elongation at ≥6%.
  • Interlayer peel strength is specified at ≥1.2 N/mm.
  • Surface resistance is specified at ≤0.05 ohm/sq and oxidation potential at ≥4.8 V vs Li/Li.
