Puxalu: composite aluminum foil completes various performance tests and is recognized by leading companies.

Putai said on the interactive platform that the cost and weight of the current collector in lithium batteries account for a significant proportion. Compared to traditional current collectors, composite current collectors have a competitive advantage in reducing weight and improving safety. On the other hand, the technological research and application of composite copper foil and composite aluminum foil will become one of the important paths to reduce the cost and improve the safety of lithium batteries. Therefore, the rising price of copper and aluminum will help promote the mass application of composite current collectors. The company has achieved unique product lines in composite current collectors through the industrial synergy of Jatao composite equipment, Zhuli composite current collectors, and Gaoyuan ultra-thin copper foil, promoting the company's composite copper foil products in all aspects from substrate, auxiliary materials, process to equipment end. Some products have been approved in product testing by top domestic customers, and it is expected that the cost after mass production will be lower than traditional copper foil; composite aluminum foil has completed various performance tests and has been approved by top enterprises. Compared with peers in the industry, the company's process solutions have the characteristics of high efficiency and low cost, have achieved small batch shipments in consumer customers, and continue to accelerate product certification in power customers.
