Who knows the models of Celgard Battery Separator can be used for lithium battery? About battery separator: These films have numerous nano-scale voids. Although they are insulating materials and cannot conduct electrons, the voids allow lithium ions to pass through. When used in lab coin cell research, it is cut into a circle with a diameter equal to the internal diameter of the positive case of t...

The principle of ultrasonic metal welding is a special method of using the mechanical vibration energy of ultrasonic frequency to connect the same metal or dissimilar metal. When the metal is ultrasonically welded, it neither transmits current to the workpiece nor applies a high temperature heat source to the workpiece, but under static pressure, the frame vibration energy is converted into fricti...

In the production process of pouch cell battery, there are many factors that can lead to abnormal gas production, which can be divided into several categories: First, the film formation of the cell itself is unstable. In the subsequent cycle process, the SEI film on the surface of the negative electrode may fall off or become loose, and the SEI film(SEI Formation Machine) is reconstructed, accompa...
