5. Machine process description:

Accurate mixing:

During mixing, a homogeneous coating paste (slurry) is produced that is applied to the electrode foils during the subsequent coating process.

Film coating:

Coating machine with various heating designed to produce films with consistent thickness. 

Calender:

Roll the dried electrode to reduce the thickness and increase the density.

Slitting:

Slit the positive and negative plates according to the width requirements.

Winding:

Place the electrode piece and separator on the winder for winding, and the stacking order is as follows: (separator+ positive + separator +negative ).

Welding:

Put the cell into the battery shell, and weld the negative electrode tab and the negative electrode shell with a spot welder.

Grooving:

The battery shell is formed by rolling groove,which is convenient for sealing.

Baking before injection:

Sealing:
