Cell assembly
Separation, stacking
Now, after the electrode manufacturing, we can move on to cell assembly.
There are a total of 4 stages for cell assembly: separation, stacking, packaging, electrolyte filling.
Separation
The first stage of cell assembly is separation.
This is a process that separate the anode, cathode, and separator sheet from the daughter rolls with a shear cut (punching tool).
The individual sheets that are cut will be stored in a magazine and stacked.
Stacking
The second stage of cell assembly is stacking.
This process stacks the sheets in a repeating cycle of anode, separator, cathode, separator, and so on.
There are many different ways to stack, and the most common one is called Z-folding.
This method inserts anode and cathode from the left and right into the z-shaped folded separator. And the cell stack is finally fixed with adhesive tapes.
