Types Of Aluminium Foil

The application advantages of aluminum alloy in power batteries: 1) The weight reduction effect is obvious: the density of aluminum is only 1/3 of that of steel, and the weight reduction effect can reach 30% to 40%. 2) Excellent performance: Aluminum alloy has high strength, good formability and excellent welding performance. 3) High recovery rate: aluminum alloy has a low melting point and is easy to remelt and recycle, with a recovery rate of over 80%. At the same time, the recycled aluminum recycling production is more than 95% energy-saving than the newly produced aluminum alloy, and the aluminum loss is only about 5%, which is conducive to reducing energy consumption and production costs, and promoting sustainable development. Recycle. .
 
 The application range of aluminum in power batteries: mainly include positive current collector, battery soft pack, battery case, cover plate, explosion-proof disk and flip cover, pole, tab, flexible connection, battery module side plate, battery box, battery tray And other aspects.
 
The battery aluminum foil is used as the positive electrode current collector of the lithium ion battery. The main function of the current collector is to provide electron channels for electrochemical reactions, accelerate charge transfer, reduce electrochemical polarization, and improve the coulombic efficiency of charge and discharge. The thickness of the battery foil is between 12 and 16 microns. Commonly used pure aluminum foils for lithium batteries have various alloy brands such as 1070, 1060, 1235, 1100, 3003, and H18.
 
The battery box and the cover plate of the square battery box are stamped by continuous multi-stage molds. AA3003 aluminum alloy material has the characteristics of good workability, corrosion resistance, good thermal conductivity, and excellent welding performance. It has been widely used in automobile power battery shells and cover plates. Dominant.

Reusable Aluminum Foil will become the first choice for catering delivery and food packaging in the future.
