- Description
- Inquiry
It is key material of soft packed lithium battery. The single battery is sealed after assembly and forms battery, thus protecting the internal battery.
Specifications
- Thickness:152μm, higher requirements for production process
- Barrier property: higher than that of ordinary aluminum plastic film
- Good puncture resistance
- Good electrolytestability
- High temperature insulation resistanceto prevent the short circuit of the aluminum foil by the metal electrode.
