Notching refers to the process where reel of electrode is cut into individual sheets with designated dimensions. Vacuum drying removes moisture from sheets of electrodes to ensure low moisture content in assembled battery cells.
The cathode and anode foils are stacked together with a separator material in between to create a jelly roll-like structure.

Tab welding connects a set electrode foils to tab.

The purpose of packaging is to place Jelly roll into formed pouch, fill with electrolyte and seal.

To help the lithium ions shuttle between the cathode and anode.
