Abstract
An energy-storage device, an electrical apparatus, and a winding method are provided in the disclosure. The energy-storage device includes an electrode and a separator, where the electrode and the separator are stacked and wound to form a cell. The electrode is connected with a tab at an end of the electrode in a width direction of the electrode, where the tab includes a first tab and at least one second tab. The first tab is positioned adjacent to an end of the electrode in a length direction of the electrode, and the first tab defines a U-shaped notch. The U-shaped notch is configured to indicate a winding end position of the electrode, facilitating identification and winding automation.
