ETEKWARE Quality Control

Material Selecting and Mixing

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. High-precision thermostatic coating machine and laser keep the same thickness tolerance less than 1µm.

Electrode Precision Manufacturing

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.

Aging & Grading Verification

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 air moisture. Our vacuum roasters bake the lithium polymer batteries under 75-80 degrees more than 36 hours adequately. Constant temperature cabinet activates the lithium polymer battery. High-precision cabinet tests the real capacity & curve of each cell.

Assemble the Batteries

The point inspection for internal resistance & voltage before assembling PCM, wires & connector. We do another testing again for the above items after collecting. Check the surface of lithium polymer 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.
