Cell Lab LCP Composite Aluminium Foil [280 mm Width]

Cell Lab LCP Composite Aluminium Foil [280 mm Width, 14 µm Thickness, 50 m/roll]

High-performance composite current collector for safer and lighter lithium-ion batteries

The Cell Lab LCP Composite Aluminium Foil is a next-generation current collector designed to enhance safety, reduce weight and improve energy density in advanced battery architectures. Featuring a multilayer configuration of Al 5 µm / LCP 4 µm / Al 5 µm, this foil integrates a Liquid Crystal Polymer (LCP) dielectric layer that prevents internal short circuits and provides near-infinite electrical resistance across the insulating barrier.

Its high-purity aluminium outer layers ensure excellent conductivity and bonding strength, while the LCP core adds exceptional thermal and mechanical stability. This composite foil is particularly suitable for lithium-ion battery R&D, pouch-cell development, and solid-state or flexible energy-storage systems requiring ultra-thin, lightweight current collectors.

FAQ

Q1: What advantage does the LCP layer provide over traditional aluminium foil?
A1: The LCP dielectric layer prevents internal short circuits and enhances mechanical and thermal safety.

Q2: Can the thickness of each layer be customised?
A2: Yes. Both aluminium and LCP layer thicknesses can be modified to meet specific research or production requirements.

Q3: How does it improve energy density?
A3: By reducing current-collector weight and integrating insulation within the foil, it increases overall cell energy per unit mass.

Q4: Is this material compatible with solid-state and flexible batteries?
A4: Absolutely. Its composite design supports flexible and high-temperature processing environments.

Q5: What are the handling and storage recommendations?
A5: Store in a dry, clean environment below 40 °C; handle with gloves to prevent surface contamination.
