How are lithium ion batteries made?

The lithium-ion battery manufacturing process generally consists of multiple stages:

Raw materials:

The basic ingredients for a lithium-ion battery, which comprise lithium cobalt oxide (LiCoO2), lithium manganese oxide (LiMn2O4), or lithium iron phosphate (LiFePO4) for the cathode and graphite for the anode, are obtained first.

Mixing:

To make a paste, the cathode and anode materials are combined with a conductive agent and a binder. The cathode and anode are then formed by spreading this mixture over thin aluminum or copper foil.

Rolling: The cathode and anode foils are rolled together with a separator in between to make a long “jelly roll” of material.

Cutting:

To make the individual battery cells, the jelly roll is sliced into little circles or rectangles.

Assembly:

Individual battery cells are then combined to form a battery pack, which may also include extra components such as a protective circuit and a thermistor.

Testing:

The battery pack is checked to verify it satisfies all requirements and safety regulations.

Packaging:

The completed battery pack is packed and sent to the customer.
