The key role of aluminum-plastic film in the field of power batteries/energy storage

As the key packaging core of soft pack lithium batteries, our aluminum pouch film balances high barrier properties and molding stability, with a three-layer structure that precisely matches industrial grade requirements: the outer layer of nylon is puncture resistant and impact resistant, the middle aluminum foil isolates water vapor and oxygen, and the inner layer of CPP is resistant to electrolyte corrosion and does not peel off, meeting the long-term reliability requirements of 153 μ m thick specification power batteries and energy storage batteries.

Guangdong btree new energy material company breaking through the limitations of traditional processes, our dry and hot methods technology significantly improves the adhesion between the aluminum layer and CPP layer. After being immersed in electrolyte, the peeling force attenuation is lower than the industry average, and the water resistance performance is improved by 20%; The dry process product has a punching depth of over 7mm, a smooth appearance without pinholes, and is suitable for the punching pit requirements of large-sized battery cells, meeting the new standards of high temperature resistance and high insulation for solid-state batteries.

From 3C consumer electronics to new energy vehicle power batteries, from household energy storage to grid level energy storage projects, our aluminum-plastic film has passed rigorous verification by multiple leading battery companies, with reasonable prices and shortened delivery cycles, providing stable support for the industry chain.
