Is the blade battery made of aluminum-plastic film?

Aluminum-plastic film for blade battery of Pacific automobile net presents sandwich structure, which consists of external resistance layer (nylon layer), barrier layer (aluminum foil) and heat sealing layer (CPP). Aluminum-plastic film has high barrier, good cold stamping formability, puncture resistance, electrolyte stability, high temperature resistance, insulation and so on, which plays a role in protecting the internal materials of the battery.

Next, let's take a look at the industrial chain of _ _ _ _ _ _ _ aluminum-plastic film.

Upstream materials include BOPA film, calendered aluminum foil, cast polypropylene, adhesive, etc.

In the downstream application field, the following soft lithium batteries are mainly used for 3C consumption, power and energy storage.

Upstream of aluminum-plastic film industry chain: the full name of raw material is BOPA film, which is an important material on the surface of aluminum-plastic film, and its main raw material is polycaprolactam (nylon

6)。 At present, the main domestic production companies are: Xiamen Su Chang, Cangzhou Pearl, Fosun Technology, Yuncheng Plastic Industry, Xiaoxing Film, Shanghai Jiutian and so on.

The main function of CPP film in aluminum-plastic film of lithium battery is heat sealing. Heat sealing makes the lithium battery have good sealing, corrosion resistance, no liquid flow, strong impact resistance and beautiful appearance, which can effectively prolong its service life. The main suppliers of cast polypropylene in China are Kangdexin and Boyi New City.

In the current industrial structure of aluminum-plastic film, the share of Japanese DNP in the world is about 50%, followed by Showa Electric and Licun Chemical, with the shares of 65,438+02% and 65,438+065,438+0% respectively, and the total market share of the three overseas enterprises is 73%.

China enterprises account for about 25% of the global share.
