Coated Carbon Aluminum Foil
1. Lithium-ion battery single/double-sided carbon coating: Primarily used for lithium iron phosphate oil-based cathodes, but can also be used for ternary or lithium cobalt oxide oil-based cathodes or lithium-sulfur oil-based cathodes (coating is not water-resistant; suitable for non-aqueous systems; highly versatile).
2. Lithium-sulfur single/double-sided carbon coating: Suitable for lithium-sulfur aqueous cathodes (e.g., PAA and SBR aqueous binders).
3. Good coating uniformity and consistency; single-sided coating thickness ~1µm, double-sided thickness ~2µm. The thickness in the specifications is substrate thickness * substrate width * roll weight. Different roll weights indicate different lengths in meters.
4. Inventory product specifications may differ from official website data; please consult customer service for details.
5. 1m² product is a sheet, approximately the size of an A4 sheet; approximately a dozen sheets are shipped (effective area 1m²).
6. Precautions for use: Seal immediately after use to avoid water absorption (especially for lithium-ion battery single/double-sided carbon coating). Storage in a dry room is recommended for better results.
Note：
Carbon-coated aluminum foil is made by uniformly and finely coating dispersed nano-conductive graphite and carbon-coated particles or other superconducting and thermally conductive materials onto aluminum/copper foil.
When used in battery current collectors, it provides excellent static conductivity, collects the micro-currents from the active material, and thus significantly reduces the contact resistance between the positive and negative electrode materials and the current collector.
It also improves the adhesion between them, reduces the amount of binder used, and consequently significantly improves various aspects of battery performance.
In other industrial applications, it improves interfacial resistance and increases electrical and thermal conductivity.
