Conductive Carbon Coated Aluminum Foil for Battery Raw Material

Carbon coated aluminum foil is a composite slurry mainly composed of conductive carbon and high-purity electronic aluminum foil, made by transfer coating technology. The use of functional coatings for surface treatment of battery conductive substrates is a groundbreaking technological innovation. Carbon coated aluminum foil is a uniform and delicate coating of dispersed nano conductive graphite and carbon coated particles on the aluminum foil.

We has independent slurry research and development technology and uniform coating technology, we can provide continuous and intermittent coating fluid collectors according to customer requirements. Intermittent size, width, blank size, and slurry system can all be customized.

As the raw material for Battery Raw Material has become an important application for carbon coated aluminum foil. The normal thickness of Conductive Carbon Coated Aluminum Foil For Battery Raw Material using about 16μm and also can Customized.

 

 

 

1.Product Structure

The primer layer technology for carbon-coated Aluminum Foil appears to address critical challenges in lithium-ion battery (LIB), particularly in improving interfacial contact, reducing stress from active material expansion, and protecting current collectors.

2.Working Method

Primer layer plays a critical role in enhancing the performance of carbon-coated Aluminum Foil for lithium-ion battery(LIB).  The primer acts as an interfacial bridge between the copper current collector and the anode active material (e.g., graphite, silicon).

It features excellent physical properties such as fine grain structure, low profile, and high elongation. In the PCB manufacturing process, it offers the advantages of short circuit etching time and highly uniform circuit etching.



It can effectively contribute to improving the energy density of lithium batteries, provides a stable, conductive substrate onto which the anode active material slurry is coated and rolled.aligning with a major trend in the development of future power battery systems for electric vehicles-lightweighting.



With advantages including light weight, high flexibility, improved electrolyte wetting efficiency, and reduced internal resistance of lithium batteries, it significantly enhances the specific energy and charge-discharge rate of lithium-ion batteries.Copper is electrochemically stable within the operating voltage window of the anode, meaning it does not alloy with lithium.



It exhibits good thermal conductivity, excellent processability, ductility, and formability, along with remarkable resistance to softening and high fatigue strength.Collects and transports electrons generated during the battery's discharge phase to the external circuit. Conversely, it distributes electrons evenly during charging
