Aluminum Foil For Battery Manufacturers

Soft pack lithium batteries, also known as polymer batteries, use aluminum-plastic film packaging in their structure. They have the characteristics of small size, light weight, high energy density, and high safety. In the event of a safety hazard, soft pack batteries may only swell and crack open, without causing explosions.

The aluminum-plastic film is mainly composed of nylon layers, aluminum foil layers, heat-sealing layers, and adhesive binder for bonding. Aluminum foil is the main raw material for the aluminum-plastic film of soft pack batteries, aluminum foil for battery manufacturers mainly supply 8021 aluminum foil and 8079 aluminum foil in the O temper. The aluminum-plastic film has high barrier properties, good cold stamping formability, puncture resistance, electrolyte stability, high temperature resistance, and insulation properties. These performance characteristics also determine the high technical requirements and demanding standards for raw materials in the production process.

Due to the strict quality requirements for the performance, plate surface, and dimensional tolerance of battery aluminum foil, it is necessary for aluminum foil for battery manufacturers to control the processing parameters, optimize the process, and conduct manual inspection to ensure product quality during the hot rolling process. Haomei Aluminum has dedicated melting furnaces, holding furnaces, casting machines, specialized three-level filtration systems, and experienced casting workers for casting battery foils. A series of standardized processes ensures excellent product quality and meets the requirements for battery aluminum foil.

Haomei Aluminum’s 8021 aluminum foil and 8079 aluminum foil used in battery soft packs have the following advantages:

1. Good deep drawing performance.
2. Good resistance to electrolyte corrosion.
3. Strong heat sealing strength.

With the development of consumer electronic products towards lightness, miniaturization, high performance, and multi-functionality, higher requirements have been placed on batteries. The demand for soft pack batteries is increasing, and the consumption of aluminum foil is also growing. As a large aluminum foil for battery manufacturer, Haomei Aluminum has been supplying 8021 aluminum foil and 8079 aluminum foil for battery soft packs for a long time. With mature technology and strict quality management system, the company ensures the provision of high-quality and satisfactory products to customers.
