Cathode active material dehydration apparatus using electroosmosis, and dehydration equipment comprising dehydration apparatus

A cathode active material dehydration method using electroosmosis, comprising:

• providing cathode active material dehydration equipment, accommodating a cathode active material that has passed through a washing process in an internal space of the cathode active material dehydration equipment, and applying an electric field to the cathode active material to remove, through electroosmosis, a washing solution remaining in the cathode active material wherein the electroosmosis suppresses residual lithium, and performing drying by heating the cathode active material in a state where the cathode active material is kept in the internal space.
