Composite metal foil has the following advantages:
Low resource dependence: Composite metal foil reduces dependence on specific metal resources by replacing part of the metal with materials such as polymers, which helps to ease resource pressure.
Low material cost: The use of polymer materials with more advantageous prices to partially replace metals can significantly reduce material costs, especially when the price of raw materials fluctuates greatly, composite metal foil has a greater price advantage.
Lightweight characteristics: Composite metal foil is usually lighter than traditional metal foil, which can improve the lightweight characteristics of the product and is suitable for equipment with strict weight requirements.
Multifunctionality: The middle layer of the composite metal foil is a polymer material, which can be given additional functions such as flame retardancy and puncture resistance by adding materials such as flame retardants to improve the overall performance of the product.
High process maturity: The manufacturing process of composite metal foil has gradually matured, and mainstream processes such as magnetron sputtering + water electroplating and evaporation have been widely used to ensure production efficiency and product quality. High safety and puncture resistance: Composite metal foil performs well in improving battery safety, can reduce the occurrence of short circuits within the battery cell, and has high puncture resistance.
