Abstract: Provided is an electrode treatment method comprising a peeling step that involves grinding, with a grinding means, an electrode in which an electrode mixture is held on a collector, and peeling the electrode mixture from the collector, the electrode treatment method characterized in that the grinding means has a first member (3) that has a grinding surface and a second member (4) that has a grinding surface, and the first member (3) and the second member (4) are disposed so that the grinding surfaces of the first member (3) and the second member (4) face each other and a space for grinding the electrode is formed between the members, and at least one among the first member (3) and the second member (4) is a grinder that rotates around the direction in which the grinding surfaces face each other and which serves as the rotational axial direction.
