Shanghai Metal Corporation is a leading Carbon Coated Aluminum Foil manufacturer and supplier.
Carbon coated aluminum foil, also called Conductive coated aluminum foil refers to the upper and lower two layers of high-purity rolled aluminum foil with a thickness of less than 50um, uniformly coated with a layer of conductive materials such as carbon nanotubes, graphene, conductive carbon black, conductive graphite and special adhesives Consists of conductive coating composite products. This product is mainly used in the positive current collector of lithium ion batteries and bipolar plates of super capacitors (EDLC). Because this product is used in the core of the lithium battery, it puts forward many demanding requirements on this product. For example, it can maintain long-term electrochemical stability at a higher voltage platform, can withstand long-term immersion of electrolyte, and can It has excellent surface contact ability, can provide excellent interface conductivity, can withstand the stress damage generated during the long-term cycle of the battery, etc.
The application of conductive coated aluminum foil can improve the peeling force of the positive pole piece of the lithium ion battery, thereby improving the battery cycle life, reducing the internal resistance of the battery, improving the charge and discharge rate of the battery, improving the charge and discharge capacity of the battery in a low temperature environment, and improving the battery In the production process, the through rate and the power of the composition make a significant contribution to the reduction of the overall cost of battery manufacturing. In addition, the application of conductive coating aluminum foil can also provide a great help in the important indicator of "battery performance consistency" in the production process of power batteries.
