l Excellent resistance to electrolyte;
When the soaking time reaches 72 hours, the composite strength and heat seal strength of the inner layer tend to be stable. The heat seal strength is stable above 50N / 15mm, and the composite strength is stable above 8N / 15mm.
Heat sealing test conditions: temperature 180 ℃, surface pressure 0.4Mpa, time 3s
Test conditions: general-purpose lithium ion secondary battery electrolyte, temperature 85 ° C.
l Excellent ductility;
Note: The design of the test mold will affect the test results.
l Excellent thickness consistency; A typical batch production test data drawing:
It is produced using imported high-precision equipment, which provides an excellent basis for its thickness control. Stable thickness consistency is very conducive to maintaining the consistency of the battery's impact resistance and other properties, which greatly reduces the defective rate of the battery due to the unstable thickness of the aluminum plastic film.
l Purification workshop, imported on-line double-sided surface scanning system to ensure the superiority of the inner and outer layers of the product.
10,000-level purification workshop, imported on-line double-sided scanning inspection with a resolution of 0.01mm², ensuring superior and consistent product appearance.
l Excellent packaging strength and good retention;
l Can be used in mobile communication terminals, tablet computers, high-performance mobile power supplies, 3C household electrical appliances, small charge and discharge equipment, thin digital products, and other thin and large-capacity battery packs;
