Abstract
An energy storage device and an electric device are provided in the disclosure. The energy storage device includes a jelly roll assembly and a connector. The jelly roll assembly includes at least one jelly roll. Each of the at least one jelly roll has multiple tabs arranged in a thickness direction of the tabs after winding an electrode sheet. The jelly roll has a first side surface and a first end surface. The multiple tabs are bent at roots of the multiple tabs and attached to the first end surface. The multiple tabs have a connection surface away from the first end surface. The connector is disposed on the connection surface and connected with the multiple tabs. The jelly roll assembly further includes a first insulation patch. The first insulation patch adheres to and covers a surface of the connector away from the first end surface, and extends to the first side surface.
