Abstract: A battery cell including an electrode assembly, a housing, and a first bonding portion. The electrode assembly includes a first end surface, and a first surface and a second surface disposed face away from each other. The housing includes a first inner wall and a second inner wall disposed opposite each other. The first bonding portion includes a first adhesive layer and a second adhesive layer. The first adhesive layer is bonded to the first end surface and extends to the first surface and the second surface to bond with the first surface and the second surface. The second adhesive layer includes a first portion, a second portion, and a third portion connected in sequence, where the second portion is located on a side of the first adhesive layer face away from the first end surface.

Abstract: The present application discloses an electrode assembly and a battery including the same. The battery includes an electrode assembly and a casing accommodating the electrode assembly. The electrode assembly is formed by winding or stacking a first electrode sheet and a second electrode sheet. A separator is disposed between the first electrode sheet and the second electrode sheet. The electrode assembly includes a first end portion, a second end portion, a first main plane, a second main plane, and a binding layer. The second end portion and the first end portion are arranged oppositely. The second main plane and the first main plane are arranged oppositely. The binding layer includes a first area arranged at the first end portion and a second area arranged at the first main plane, and the first area is connected to the second area.
