Zusammenfassung:A cylindrical battery, a battery assembly, and an electrical apparatus are provided. The cylindrical battery includes a casing (3), a cell (4), and a current-collecting plate (5, 5', 5"). One end wall (32, 33) of the casing (3) is formed with a discharge zone (331) to form a weakened end wall. An orthographic projection of the discharge zone (331) towards the current-collecting plate (5, 5', 5") overlaps at least a portion of the current-collecting plate (5, 5', 5"). The current-collecting plate (5, 5', 5") includes at least one extension portion (51) extending from a circumferential outer edge of the weakened end wall to within a range of the orthographic projection, and within the range of the orthographic projection, the extension portion (51) is configured to be adapted to be folded away from the corresponding end portion of the cell (4).
