Abstract: A battery cell includes an electrode assembly, an outer surface of the electrode assembly includes a first surface, a first side surface, a second surface, and a second side surface, a first end surface and a second end surface. The battery cell further includes: a first adhesive film adhered to the first side surface and extending from the first side surface to the first surface and/or the second surface; and a first adhesive layer adhered to the first surface and extending from the first surface to the second surface through the first end surface, where in a width direction of the electrode assembly, there is a first overlapping portion between the first adhesive film and the first adhesive layer on the first surface and/or the second surface. This application further provides a battery including the battery cell and an electric device.

Abstract: A secondary battery, including an electrode assembly and a housing accommodating the electrode assembly. The electrode assembly includes a first electrode plate, a second electrode plate, and a separator disposed there between. The first electrode plate and the second electrode plate are wound to form the electrode assembly. A tab is disposed in the first electrode plate and protrudes from the housing; and an adhesive layer is disposed in the tab. The adhesive layer includes a first portion sandwiched between a package area of the housing and a second portion extending from the first portion along a length direction of the tab. In a width direction of the tab, the first portion has a width greater than that of the second portion. In the length direction of the tab, the second portion protrudes into a space enclosed by an innermost layer of the separator.
