CONTINUOUS POSITIVE ELECTRODE ACTIVE MATERIAL ELECTRIC DEHYDRATION APPARATUS

WIPO Patent Application WO/2024/043573

A1

The present invention provides a continuous positive electrode active material electric dehydration apparatus comprising: a rotating drum including a first electrode; a transfer member which moves with a positive electrode active material resting thereon and continuously transfers the positive electrode active material to the drum; and a guide device which surrounds a portion or the entirety of the drum, includes a second electrode generating an electric field by means of the potential difference with the first electrode, and causes cleaning solution remaining on the positive electrode active material introduced by the transfer member to be electrophoretically dehydrated by the electric field, wherein the positive electrode active material is pressed between the outer peripheral surface of the drum and the guide device when the transfer member moves between the outer peripheral surface of the drum and the guide device. Therefore, the apparatus has the advantage that the positive electrode active material can be continuously dehydrated by being introduced between the rotating drum and the guide device.
