  "textContent": "A battery cell includes an electrode assembly including a first surface, lateral faces, and a second surface connected in a thickness direction of the electrode assembly, the first surface is disposed opposite to the second surface. A tab is electrically connected to the electrode assembly and led out from one of the lateral faces. A tab lead is connected to the tab by welding to form a weld region. An adhesive layer fully overlays the weld region and two ends of the adhesive layer are disposed on two opposite surfaces of the electrode assembly. Area of fixation between the adhesive layer and the electrode assembly is relatively large, and adhesive layer is highly adhesive and not prone to peel off, thereby preventing burrs in the weld region from contacting housing of the battery, reducing the risks of corrosion and electrolyte leakage, and ensuring high efficiency of top sealing of the battery cell.",
