  "textContent": "A jelly-roll battery cell includes a first electrode plate, a second electrode plate, and a separator, and includes a central region enclosed by the first electrode plate, the second electrode plate, and the separator, and has a thickness direction. The first electrode plate includes: a first current collector, where the first current collector includes a first surface and a second surface opposite to the first surface, and the first surface is closer to the central region than the second surface; a first section; and a second section, where a first tab is disposed on the first surface in the second section. The second electrode plate includes a second tab whose first side is on the second electrode plate. The first end, the first tab, and the second tab do not overlap in a thickness direction.",
