  "textContent": "A tab welding structure and a battery are provided, relating to the field of battery technology. The tab welding structure includes a wound body with an electrode plate, and a full tab. The full tab is electrically connected to the electrode plate and located at one end of the wound body. A current collector is welded to the full tab to form welding point groups. The welding point groups are arranged in a radial pattern around a center of the wound body. Each welding point group includes welding points arranged in a wave pattern along a radial direction of the wound body. This configuration enhances the uniformity of current conduction in the wound body and reduces the amount of current loss.",
