This application relates to an electrode processing apparatus and a battery production system. After the electrode tab is cut out by the cutting assembly, the removal part located downstream of the cutting assembly can contact the electrode tab through the abrasive part. Through friction, the fine molten bead particles attached to the cutting edge of the electrode tab and nearby are effectively removed, reducing the number of these particles remaining on the electrode and subsequently entering the battery. This reduces problems such as internal short circuits and performance degradation caused by particles, and effectively improves the reliability of the battery after production.
