7 Mic Aluminum Foil

Aluminum foil is available in a range of thicknesses, typically falling between 0.006 and 0.2mm.

7 mic aluminum foil is commonly used in the new energy industry, specifically for lithium-ion (Li-ion) batteries and sodium-ion batteries. Li-ion batteries are widely used in various applications, including electric vehicles, portable electronic devices, and renewable energy storage systems.

In addition to the 7 Mic Aluminum Foil, there are other common thicknesses for aluminum foil:

  • 0.006mm (6 microns)
  • 0.010mm (10 microns)
  • 0.012mm (12 microns)
  • 0.015mm (15 microns)
  • 0.018mm (18 microns)
  • 0.020mm (20 microns)
  • … …
  • 0.2mm (200 microns)

Li-ion battery:

In Li-ion battery manufacturing, the 7-micron aluminum foil is utilized as a crucial component in the battery’s construction. It is typically used as a current collector, which helps facilitate the flow of electrons during the charging and discharging processes.

The thin 7-micron thickness of the aluminum foil allows for efficient and lightweight battery designs. It provides excellent electrical conductivity, ensuring optimal performance and energy transfer within the battery. Additionally, the foil’s high surface area allows for improved adhesion of active materials, enhancing the overall battery performance and stability.

Sodium-ion batteries:

In sodium-ion batteries, aluminum foil is commonly used as the current collector even more so than in lithium-ion batteries. Sodium-ion batteries are an emerging energy storage technology widely applied in large-scale energy storage systems, grid regulation, and renewable energy integration.

The aluminum foil used in sodium-ion batteries typically comes in different thicknesses, depending on specific application requirements. Common thickness ranges include 7 microns, 10 microns, and 12 microns. Aluminum foil plays a crucial role in sodium-ion batteries by serving as the current collector and facilitating efficient electron flow during the battery’s charge and discharge processes.

Similar to lithium-ion batteries, aluminum foil in sodium-ion batteries requires good electrical conductivity and dimensional stability to ensure high performance and long cycle life. The lightweight nature of aluminum foil also contributes to increased energy density and overall efficiency of the battery.

As sodium-ion battery technology continues to advance, the demand for aluminum foil with enhanced properties to meet higher performance and more stringent application requirements is increasing in the new energy industry. Therefore, the usage of aluminum foil in sodium-ion batteries is growing more prevalent.
