Abstract
An electrode assembly and related battery, device, manufacturing method, and manufacturing device are provided. In some embodiments, the electrode assembly includes: a first electrode plate and a second electrode plate that are of opposite polarities, where an active material region of the first electrode plate and an active material region of the second electrode plate are wound to form a body portion, a non-active material region of the first electrode plate or a non-active material region of the second electrode plate is wound to form a tab, and the tab includes a bend portion bent against the body portion; and a guide piece. At least a part of the guide piece is located in the bend portion, and the guide piece is configured to guide an electrolytic solution into an interior of the body portion.
