Materials of LiPoly Battery
The graphite, pure water & lithium cobalt oxide we purchase from quality material suppliers. They are put into a vacuum high-speed stirring machine more than 12 hours to ensure that the density of the entire cylinder of raw materials.
Coating of LiPoly Battery
High-precision thermostatic coating machine and laser keep the same thickness tolerance less than 1µm.
Sheeting of LiPoly Battery
Precision automatic roll machine to ensure the height of the pole piece of the same thickness; ultrasonic welding makes pole pieces 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.
Wrapping of LiPoly 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 lipoly battery to insulate of air moisture.
Baking of LiPoly Battery
Our vacuum roasters bake the lithium polymer batteries under 75-80 degrees more than 36 hours adequately.
Aging & grading of LiPoly Battery
Constant temperature cabinet activates the lipoly battery. High-precision cabinet test the real capacity & curve of each cell.
Assembling of LiPoly Battery
The point inspection for internal resistance & voltage before assembling PCM, wires & connector. We do another testing again for the above items after collecting.
Packing of LiPoly Battery
Checking each the surface of lipoly battery & quantity when we put them into the groove of plastic trays. All trays are fixed by wrapping film without rocking. Sturdy cartons are fit for internal shipment by air or by sea.
