WET SIMULTANEOUS BIAXIAL STRETCHING SEPARATOR
We have introduced the simultaneous biaxial stretching production line, and based on the years of manufacturing technology and experience in the simultaneous biaxial stretching film, optimized the material formula to achieve the exact control of the production. After the wet separator project was established, Cangzhou Mingzhu targets Japanese and Korean separator companies and the advanced s simultaneous biaxial stretching production process to make our wet separator products perform better.
Thin thickness: good consistency; High security.
Thin in thickness: The 5-micron wet ultra-thin separator products are more suitable to be applied in small consumer electronic products. It can better meet the demand of increased energy density and power performance for the digital Li-ion battery.
High consistency: The more uniform microporous structure and pore size distribution of the Cangzhou Mingzhu simultaneous wet separator ensures consistency in the ion conduction performance of Li-ion batteries. During the long-time charging and discharging, it can reduce the loss of active material and electrolyte and prolong the battery cycle life.
Good safety performance: Cangzhou Mingzhu simultaneous biaxial stretching wet separator is characterized by highly consistent in longitudinal and transverse strength and high puncture strength, able to reduce the short circuit risks within the battery caused by the lithium metal dendrite puncture; by optimizing the material formula, Cangzhou Mingzhu wet separator has the advantages of low thermal shutdown temperature, high film rupture temperature and good high-temperature stability, conducive to improving the Li-ion battery safety.
