  "textContent": "Embodiments of the present application provide an electrode assembly, a battery cell, a battery, and a method and a device for manufacturing an electrode assembly, which belong to the technical field of batteries. Embodiments of the present application provide an electrode assembly including a first electrode plate and a second electrode plate. The first electrode plate and the second electrode plate are wound along a winding direction to form a winding structure, and the winding structure includes a bending region. The first electrode plate includes a first segment that exceeds a winding starting end of the second electrode plate, and at least a part of the first segment is configured to provide a support force to a part of the first electrode plate and the second electrode plate in the bending region and located at an outer side the first segment, making a structure of the first electrode plate and the second electrode plate more compact in the bending region. And a gap between the part of the first electrode plate in the bending region and the part of the second electrode plate in the bending region is not easy to be expanded by an external force and the occurrence of lithium plating is reduced.",
