Abstract: A device for removing a coating material from a battery electrode plate is provided. The battery electrode plate includes a current collector and a coating material attached to a surface of the current collector. The device includes a housing, a spraying port, and a suction port. The housing includes a side plate. A hollow space is defined by the side plate. The side plate is configured to be in contact with the current collector to isolate a portion of the coating material in the hollow space. The spraying port is located in the hollow space, and configured to be in communication with a liquid source to spray a liquid onto the portion of the coating material to dissolve the coating material. The suction port is located in the hollow space and configured to be in communication with a vacuum generation device to suck the dissolved coating material away from the current collector.
