Top 10 lithium battery aluminum-plastic film manufacturers in China in 2022

According to the different packaging forms, lithium batteries can be divided into square batteries, cylindrical batteries and pouch batteries. Square and cylindrical batteries are mostly packaged with steel or aluminum shells, and pouch batteries are mostly packaged with aluminum-plastic film.

Due to the presence of electrolyte inside the battery, the aluminum-plastic film of the pouchage material is required to be able to resist the swelling, dissolution and absorption of organic solvents (electrolyte), while ensuring strict barrier of oxygen and moisture.

Aluminum plastic film is generally composed of nylon layer, adhesive layer, aluminum foil, protective layer, adhesive layer, and CPP layer. After the single cell battery is assembled, it is sealed with an aluminum-plastic film to form a battery, and the aluminum-plastic film plays a role in protecting the contents.

The composition of aluminum plastic film

The advantage of the pouch battery lies in its high energy density. The energy density of the ternary pouch cell is 260wh/kg, while the ternary square and cylindrical cells are 240wh/kg and 250wh/kg respectively; A security problem will only bulge but not explode. But the pouch battery also has the disadvantage of high cost, which is about 50% higher than the equivalent square and cylindrical batteries.

However, the advantages of high energy density and thinness still make pouch batteries shine in the 3C consumer market. As of 2020, the global consumer lithium battery market size is 92.1GWh, and the pouch lithium battery penetration rate is 81.1%.

pouch batteries shine in the 3C consumer market

As far as the power market is concerned, pouch batteries are used more countrys, which are very popular among European car companies. In the global installed capacity ranking in 2020, the top ten power battery companies such as LG Chem, SKI, Envision AESC, etc. are mainly pouch batteries. In 2020, 15 of the top 20 electric vehicles sold in Europe use pouch batteries. However, the current China share of pouch batteries is relatively low.

In the first quarter of 2021, the China battery factory’s pouch machines accounted for 3.5GWh, accounting for 8%, and the absolute value and proportion of installed capacity were low.

However, China power battery companies have also begun to implement the pouch model. BYD announced at the DMI press conference that it will start to use pouch lithium iron phosphate (also known as small blades) and use secondary sealing technology, that is, the cells are made of pouch (aluminum-plastic film) package, the blade battery is packaged in a duralumin case.

Even under the current penetration rate, the global demand for aluminum-plastic film will be 260 million square meters in 2021, and will reach 820 million square meters in 2025, corresponding to a market space of 6.6 billion yuan in 2021 and 14.7 billion yuan in 2025.

From the perspective of the aluminum-plastic film industry chain, upstream materials include calendered aluminum foil, nylon, adhesives, polypropylene and other materials, and the midstream includes processing equipment, testing equipment, etc., and related industries will usher in development opportunities.

At present, the aluminum-plastic film market is mostly occupied by many companies, especially in the power and high-end consumer markets. With the rapid growth of the global electric vehicle market and the relatively conservative expansion of Japanese-style companies, it may bring alternatives to China aluminum-plastic film companies. Chance.
