The invention discloses a coated pole piece, a manufacturing method of the pole piece, the pole piece, a battery cell, a battery pack and a vehicle, the coated pole piece comprises a current collector, the current collector is provided with a plurality of dressing areas, and the current collector is provided with a first end and a second end in the arrangement direction of the dressing areas, the current collector forms a tab processing area on one side, facing the first end, of each dressing area; and the dressing is coated on the plurality of dressing areas. According to the coated pole piece disclosed by the embodiment of the invention, a dressing area does not need to be cut when a single pole piece is processed, so that the deviation of the dressing width of the single pole piece is effectively avoided, the consistency of the pole piece is favorably improved, the battery cell capacity consistency is better, a pole lug processing area is not easy to wrinkle, and the yield is higher.
本发明公开了一种涂布极片、极片的制作方法、极片、电芯、电池包和车辆,所述涂布极片包括:集流体,所述集流体具有多个敷料区域,且所述集流体在多个所述敷料区域的排列方向上具有第一端和第二端,所述集流体在每个所述敷料区域的朝向所述第一端的一侧形成极耳加工区域;敷料,所述敷料涂覆于多个所述敷料区域。根据本发明实施例的涂布极片在加工出单幅极片时不需要对敷料区域进行分切,有效地避免了单幅极片的敷料宽度存在偏差,有利于提高极片的一致性,以使电芯容量一致性更好,且极耳加工区域不易发生打皱,良品率更高。
