Soft-pack lithium batteries have many advantages such as high safety performance, light weight, high energy density, low internal resistance, good cycle performance, and long service life. They are widely used in equipment that requires weight and compact space, such as various electronic products and new energy vehicles. The soft-pack lithium battery uses aluminum-plastic film as the casing, which is not only light in weight, but also has higher safety.
8021 aluminum foil and 8079 aluminum foil are mainly used for the battery soft pack aluminum foil. In the three-layer structure of the aluminum-plastic composite film, the aluminum foil is used as the middle layer to prevent the infiltration of moisture from the outside of the battery and the leakage of the internal electrolyte. The soft pack battery is made of aluminum-plastic film, which makes the battery thinner and lighter than ordinary liquid lithium batteries. And when there is a problem inside the battery, it can be immediately manifested through the outer packaging. Even if there is a safety hazard, it will not explode, but will only swell.
8021 aluminum foil has excellent moisture-proof performance, shading and high barrier capacity, non-toxic, tasteless, safe and hygienic, and is the main product of food packaging and battery soft packaging aluminum foil. The thickness range of Mingtai 8021 aluminum foil is 0.018mm-0.2mm, and the width can be controlled at 100-1650mm according to customer requirements.
