The Li-ion secondary battery is classified into the cylindrical battery and the prismatic battery. The Li-ion secondary battery is completed through the process where metal foil (Al or Cu foil) is coated with cathode/ anode active materials, a separator is inserted and rewound between both electrodes and inserted into a metal container, which is filled and sealed with electrolytes. The Li-ion secondary battery is composed of anodes, cathodes, separators, electrolytes, metal cases and other components. A manufacturing process of the Li-ion secondary battery is largely divided into the following three processes.

Manufacturing processes of Li-ion secondary battery can be divided into three as followings.

1. Electrode process: mixing, coating/drying, pressing, cutting(slitting)
2. Assembling process: winding, inserting jelly roll and electrolyte, sealing
3. Inspection and chemical process

This report is about electrode process for Li-ion secondary battery. The general manufacturing process for Li-ion secondary battery is as follows.

Mixing -> Coating  -> Roll Pressing -> Slitting (Punching) -> Vacuum Drying -> Assembling ->  Aging -> Degassing -> Grading  -> Packing

This report covers to Vacuum Drying Process of anode or cathode materials from Mixing Process
