摘要： Embodiments of the present application provide a battery cell, a battery, an electrical device, and a manufacturing method and device for the battery cell, which belong to the technical field of batteries. Herein, the battery cell comprises an electrode assembly, a housing and an end cap. The electrode assembly has a first tab. The box has an opening for receiving the electrode assembly. The end cap comprises a cap body and a first convex part, the cap body is used to connect with the housing and cover the opening, and the first convex part protrudes from the inner surface of the cap body towards the electrode assembly and abuts against the first tab. The end cap is provided with a liquid injection hole, and the liquid injection hole is located inside of the outer peripheral surface of the first convex part. The first convex part is provided with a flow guiding channel, the flow guiding channel communicates with the liquid injection hole and penetrates the outer peripheral surface, and the flow guiding channel is used for allowing at least part of the electrolyte solution to flow to outside of the outer peripheral surface. During the process of injecting the electrolyte solution into the battery cell through the injection hole, the electrolyte solution can flow laterally to outside of the outer peripheral surface of the first convex part through the flow guiding channel, which can effectively improve the injection efficiency.
