Electrode manufacturing process for lithium ion batteries


Electrode Manufacturing Process For lithium ion batteries:


Mixing:

This step involves mixing active materials with appropriate particle size with binder and conductive carbon. Mixing is done for different length of time depending upon the starting material, application needs, final viscosity of the slurry etc.,

Coating:

Slurry obtained from the mixing process slowly poured on the substrate foil (Copper or Aluminum) in a controlled way. The slurry is then spread uniformly on to the substrate and partially dried. Small area on the side of the electrode is not coated usually.  This small area will later be cut into tabs/terminals.

Calendaring:

Then it is pressed and dried.  During this process the electrode is pressed and passed through number of rotating cylinders.

Drying:

The electrode is then dried and may be pressed again.

Slitting:

During this process the electrode is cut according to the required width and rolled.  This finished electrode will be used for manufacturing cells.

  1. Generally I do not understand material on weblogs, but I would like to say that this write-up very forced me to examine out and do it! Your way of composing has been amazed me. Thanks, quite awesome material..
