& Product Description
In the structure of the lithium battery, separator is one of the key component. The properties of the separator determines of interface structure, resistance of battery,directly influencing the capacitance, circulation,safety and other properties. High performance separator is very important to improve the comprehensive performance of the lithium battery.

The main function of the separator is to separate the positive and negative pole, in case of the short-circuiting due to the contact of the two poles. Furthermore, it also help the electrolytions pass through. The material of the separator is non-conductive. Its physical and chemical properties have a great impact on battery performance.The parator will be different according to types of batteries. For Lithium battery series, the electrolyte is an organic solvent system,whic is requires a solvent resistance separator material,generally using high strength porous polyolefin film.

# Features of Lithium Battery Film:
1. Having stable thickness uniformity by means of the advanced air knife adhibiting technology
2. Having good solvent resistance, electrochemical and stable properties by introducing the imported raw material
3. Using monolayer dry biaxial tension technology withour solvent and inorganic filter.
4. The entire production process is done in an environmental clean room free from contamination
5. With high temperature resistance, low heat shrink
6. Product thickness and ventilation property can be designed according to customer demand
7. High longitudinal and transverse tensile strength.

# Applications of Lithium Battery Film:
1. Mobile Phone
2. MD,MP3 player
3. Digital camera, Video camera
4. PDA, notebook PC
5. HEV batteries
6. Other hi-tech equipments
