Abstract
An electrode assembly includes a first electrode sheet, a second electrode sheet, and a first separator. The first electrode sheet and second electrode sheet are of opposite polarities, the first separator is configured to separate the first electrode sheet and the second electrode sheet. The first electrode sheet, the second electrode sheet, and the first separator are wound in a winding direction. The electrode assembly has a bending region. The bending region is provided with a second separator that is laminated with the first separator and configured to separate the first electrode sheet and the second electrode sheet adjacent to each other. At least part of ions deintercalated from the first electrode sheet are able to pass through the first separator and the second separator and be intercalated in the second electrode sheet.
