Materials of Li Polymer Battery
Production Process
The graphite, pure water & lithium cobalt oxide we purchase from quality material suppliers. They are put into a vacuum high-speed stirring machine for more than 12 hours to ensure that the density of the entire cylinder of raw materials.
Coating of Li Polymer Battery
Quality Control Video for Li Polymer Battery Production
The sheet of Li Polymer Battery
High-precision thermostatic coating machine and laser keep the same thickness tolerance less than 1µm.
Wrapping of Li Polymer Battery
Precision automatic roll machine to ensure the height of the pole piece of the same thickness; ultrasonic welding makes pole piece and perfect pole combination, welding firm, low resistance. Hundreds of points knife mold, so you no longer need to open a small batch of mold trouble.
Baking of Li Polymer Battery
We bought aluminum-plastic film from Japan without wrinkles, rupture. The automatic winding machine makes the consistency of the core volume. The high-temperature sealing machine seals the edge of lithium polymer battery to insulate of air moisture.
Aging & grading of Li Polymer Battery
Our vacuum roasters bake the lithium polymer batteries under 75-80 degrees more than 36 hours adequately.
