Soft Pack Foil

The battery soft pack foil is used in various types of lithium batteries such as soft pack lithium batteries and polymer lithium batteries. The battery soft pack foil is a layer of polymer shell on the liquid lithium-ion battery.
The soft pack battery has two layers. The outside layer is made of 8021 aluminum foil, plastic film, special glue, which forms an aluminum-plastic film. The inside layer is 1235/1060/1070 aluminum coated with lithium iron phosphate and the lithium manganate ternary material.
In the case of potential safety hazards, the soft-pack battery will only deflate at most, and will not explode like the battery with metal shell.


Product Name: Aluminum Soft Pack Foil

(1) Good safety performance: The soft aluminum foil of the battery allows the electrolyte in the battery to leak less, and the soft pack battery will burst when the safety hazard occurs, instead of the internal pressure over the hard-shell battery. explosion;
(2) Light weight: the density of flexible packaging aluminum foil is small, the weight of the soft pack battery is 40% lighter than the steel shell square battery of the same capacity, and 20% lighter than the aluminum shell square battery;
(3) Large battery capacity: The soft bag saves 20% of the volume, 50% higher than the steel shell battery of the same size, 20~30% higher than the aluminum shell battery;
(4) Good cycle performance: the cycle life of the soft pack battery is longer, and the attenuation of 100 cycles is 4% to 7% less than that of the aluminum case;

Application and After-sale Services:

Soft pack batter is lighter, safer and of longer service life, it is widely used for electric bicycles, electric vehicles, electric tools, electric toys, emergency lighting, portable power supplies and mine safety equipment.
