Lithium Battery cells Manufacturing Process


Lithium battery requires highly strict and complex manufacturing techniques and technologies that mainly comprise the following steps.


1. Paste Mixing:

This process involves mix of battery paste additives to produce active positive and negative electrode materials under high-speed stirring in a mixing machine.


2. Electrode Coating

The active electrode materials are evenly applied to both sides of metallic foils. The coated foils are then dried and baked before proceeding to the cutting machine .


3. Assembly:

The assembly process mainly consists of casting anode and cathode plates and placing a separator between the anode and the cathode. There are two different electrode structures used depending on the types of casing, a stacked structure for prismatic cells and a spiral wound structure for cylindrical cells.


4. Prismatic Cells

If a slim pack is desired, prismatic cells are often used to optimize the use of space for high capacity battery applications.


5. Formation:


Once the assembly is completed, each cell has to be put through at least one precisely controlled charge/discharge cycle to activate the materials, transforming them into their useable form.
