Classification of battery foil

Mingtai Aluminum's aluminum foil products are widely used in industries such as new energy batteries, electronics and electrical appliances, and food and drug packaging. Among them, battery foil can be divided into lithium battery aluminum plastic film foil, lithium battery current collector battery foil, negative electrode aluminum foil for electrolytic capacitors, high-purity aluminum foil for super capacitors, etc., which can be used in the field of new energy.

At present, the company's battery foil and electronic foil account for more than 20% of all aluminum foil products, and are increasing year by year. The company's lithium battery aluminum plastic film battery foil market share is relatively high.

Battery foil and lithium battery

The soft pack battery is composed of a battery foil (8021 aluminum foil 0.04mm thickness), plastic film and special glue, which are collectively called an aluminum plastic film, and a plain aluminum foil (1235 aluminum foil / 1060 aluminum foil / 1070 pure aluminum 0.012-0.016mm thickness) The surface is coated with the ternary materials of lithium iron phosphate and lithium manganate to make a soft-packed battery core. The prepared core is placed in a good aluminum plastic film to make a battery for electronic products that is commonly used now instead of More lead-acid batteries. This is what everyone says about lithium batteries.

The role of battery foil

In the three-layer structure of the aluminum-plastic composite film, the battery foil serves as an intermediate layer, which mainly prevents the infiltration of water vapor from the outside of the battery and prevents the leakage of the internal electrolyte. In order to ensure the long-term stable and safe operation of the battery, the battery foil needs to have extremely high barrier properties, good cold stamping formability, puncture resistance and stability.
