  "textContent": "Embodiments of the application provide a battery cell (7), a manufacturing method and a manufacturing system therefor, a battery and an electric device. According to the embodiments of the application, the battery cell (7) includes: an electrode assembly (10) including a first electrode piece (11); a housing (20), configured to accommodate the electrode assembly (10) and including an electrode lead-out portion; an adapter (40), configured to electrically connect the electrode lead-out portion and the first electrode piece (11). The first electrode piece (11) is configured such that the first electrode piece (11) is at least partially wound around the adapter (40) and affixed to the adapter (40). The first electrode piece (11) is wound around the adapter (40), such that a part of the first electrode piece (11) can be affixed to the adapter (40) by its own tension to ensure electrical connection between the first electrode piece (11) and the adapter (40). In this case, the first electrode piece (11) does not need to be connected to the adapter (40) by a welding process, thereby reducing metallic particles generated during production of the battery cell (7) and reducing the risk of short circuit. A part, affixed to the adapter (40), of the first electrode piece (11) is in surface contact with the adapter (40), thereby increasing the contact area between the first electrode piece (11) and the adapter (40) and increasing the current passing capacity.",
