The aluminum plastic composite film, referred to as aluminum plastic film, is a composite flexible packaging shell material used to package lithium-ion batteries and is often used in soft pack batteries and blade batteries.
The aluminum plastic film must be constructed of three layers of materials held together with adhesives in order for it to have the aforementioned properties. The structure is the outer resistance layer, the barrier layer, and the heat sealing layer from the outside to the inside.
The aluminum plastic film is a crucial material in the lithium battery industry chain’s upstream packaging, representing 10-20% of total material cost for pouch batteries.
Layer by Layer: Crafting the Protective Shell of Battery Pouch Films The manufacturing begins with surface treatment on one side of the aluminium foil, which is core layer of the pouch will provide the shape and barrier properties of the composite, the treatment enables adhesion of other polymers onto the foil.
Lithium ion cell manufacturers use laminated aluminium film to form the packaging for their pouch cells. This is a material made up of aluminium foil sandwiched between multiple layers of polymers such as PET, PA and CPP.
Lithium ion cell manufacturers use laminated aluminium film to form the packaging for their pouch cells. Please find our downloadable datasheets.

Aluminum shell batteries are the main shell material of liquid lithium batteries, which is used in almost all areas involved. The pouch-cell battery (soft pack battery) is a liquid lithium-ion battery covered with a polymer shell.
They are environmentally friendly and lighter than steel while having strong plasticity and stable chemical properties. Generally, the material of the aluminum shell is aluminum-manganese alloy, and its main alloy components are Mn, Cu, Mg, Si, and Fe. These five alloys play different roles in the aluminum shell battery.
Among all cell components, the battery shell plays a key role to provide the mechanical integrity of the lithium-ion battery upon external mechanical loading. In the present study, target battery shells are extracted from commercially available 18,650 NCA (Nickel Cobalt Aluminum Oxide)/graphite cells.
A Lithium-ion battery consists of positive electrode, negative electrode, electrolyte, diaphragm, etc. and shell packaging. According to the different shell packaging materials, the overall packaging of lithium-ion battery shell can be divided into steel shell, aluminum shell, and soft-coated aluminum-plastic film.
At HDM, we have developed aluminum alloy sheets that are perfect for cylindrical, prismatic, and pouch-shaped lithium-ion battery cases based on the current application of lithium-ion batteries in various fields. Our aluminum alloy materials are user-friendly, compatible with various deep-drawing processes.

Generally, the negative electrode of a conventional lithium-ion cell is made from . The positive electrode is typically a metal or phosphate. The is a in an . The negative electrode (which is the when the cell is discharging) and the positive electrode (which is the when discharging) are prevented from shorting by a separator. The el. A lithium-ion battery has a high energy density of up to 330 watt-hours per kilogram (Wh/kg). In comparison, lead-acid batteries typically provide about 75 Wh/kg. [pdf]
Today’s lithium ion batteries have an energy density of 200-300 Wh/kg. I.e., they contain 4kg of material per kWh of energy storage. Technology gains can see lithium ion batteries’ energy densities doubling to 500Wh/kg in the 2030s, trebling to 750 Wh/kg by the 2040s, and the best possible energy densities are around 1,250 Wh/kg.
Lithium-ion batteries generally have energy densities between 150 to 250 Wh/kg, while lithium-sulfur (Li-S) batteries can theoretically reach 500 Wh/kg or higher, and lithium-air batteries could surpass 1000 Wh/kg in ideal conditions. However, practical issues like cycle life and material stability limit these potentials in real-world applications.
