Lithium battery diaphragm production workshop pictures

What is the function of the diaphragm in a lithium battery?

Diaphragm is one of the important inner members in the structure of lithium battery. The characteristics of the diaphragm determine the page structure and internal resistance of the rechargeable battery. It immediately endangers the capacity, circulation system and safety factor of the rechargeable battery.

What are the production steps in lithium-ion battery cell manufacturing?

Production steps in lithium-ion battery cell manufacturing summarizing electrode manufacturing, cell assembly and cell finishing (formation) based on prismatic cell format. Electrode manufacturing starts with the reception of the materials in a dry room (environment with controlled humidity, temperature, and pressure).

How is the quality of the production of a lithium-ion battery cell ensured?

The products produced during this time are sorted according to the severity of the error. In summary, the quality of the production of a lithium-ion battery cell is ensured by monitoring numerous parameters along the process chain.

Is vacuum deposition a safe method for lithium ion battery manufacturing?

The vacuum deposition technique is generally a slow and expensive method, making it incompatible with the current industrialization speed of lithium-ion battery manufacturing. Moreover, there are safety concerns due to the lithium metal used.

How is lithium deposited in a vacuum chamber?

Vacuum deposition of lithium metal onto the anode: Vaporized lithium metal is deposited in a vacuum chamber onto the anode electrode to form a lithium layer of generally <10 µm.

What are the benefits of lithium ion battery manufacturing?

The benefit of the process is that typical lithium-ion battery manufacturing speed (target: 80 m/min) can be achieved, and the amount of lithium deposited can be well controlled. Additionally, as the lithium powder is stabilized via a slurry, its reactivity is reduced.
