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 55N / 15mm, and the composite strength is stable above 10N / 15mm.
Heat sealing conditions: temperature 180 ℃, surface pressure 0.4Mpa, time 3s
Electrolyte resistance 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, online 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 It can be applied to the outer packaging of soft-packed power batteries that require safety, good performance, and high-power charging and discharging, such as vehicle power supplies, energy storage components, high-powered unmanned machinery, and electric tools;
