    Abstract: A battery includes a housing, an electrode assembly, a first bonding part, and a second bonding part. The electrode assembly includes a body portion and a first metal portion. The first metal portion protrudes from the body portion along a first direction. The body portion includes a first protruding portion, a first portion, and a second protruding portion that are connected in sequence. The first portion includes a first surface and a second surface disposed opposite to each other in the second direction. The first protruding portion includes a third surface located on a same side as the first surface and a fourth surface disposed opposite to the third surface. The second protruding portion includes a fifth surface located on the same side as the first surface and a sixth surface disposed opposite to the fifth surface. The first protruding portion includes a seventh surface in the first direction.
