Output of Aluminium Foil for Aluminium-Plastic Membrane in China will Grow Rapidly to more than 100,000 mt by 2025 amid the Booming New Energy Battery Industry

SHANGHAI, Aug 19 (SMM) - According to their shape, lithium batteries can be divided into square batteries, cylindrical batteries and soft-packed batteries. The soft-packed battery is packed with an aluminium-plastic composite membrane. Once there is a safety problem, the soft-packed battery will usually inflate, crack and then leak out, and it will not explode like the hard-shell battery. In short, the soft-packed battery has the advantages of high safety performance, flexible appearance, lightweight, etc.

Aluminium-plastic composite membrane is an important material for packaging soft-packed battery cells. The membrane is composed of three layers, one of which is the aluminium foil for the aluminium-plastic membrane. According to the SMM survey, thanks to the rapid development of China's new energy market and the excellent performance of soft-packed batteries, soft-packed batteries become the most widely used battery type in 3C products at present, with a penetration rate of more than 80%. However, it accounts for less than 20% of both new energy vehicles and energy storage batteries. The use of soft-packed batteries in energy storage batteries and new energy vehicles is expected to further increase in the future, and the prospect is extremely considerable.
According to an SMM survey, at present, about six domestic enterprises are producing aluminium foil for aluminium-plastic membrane in batches, with an annual output of about 21,500 mt. And all of them are powerful first-class aluminium foil enterprises.
Meanwhile, the new capacity of aluminium foil for the aluminium-plastic membrane of many enterprises is also progressing in an orderly manner. The production capacity that has not yet been put into production in China is about 56,000 mt, which will be put into production one after another before 2024. With the rapid expansion of the new energy battery industry and the gradual maturity of production technology of aluminium foil enterprises in China, the output of aluminium foil for the aluminium-plastic membrane will grow rapidly to more than 100,000 mt by 2025.
