    摘要： An electrically conductive holder is provided that is suitable for receiving a tablet electrode of a button battery. The holder includes a bottom portion to be fitted coaxially within terminal of a button battery. The holder further includes an upstanding wall portion. The bottom portion is flat and provided with a plurality of apertures through the complete thickness of the bottom portion. At least one group of apertures is distributed at regular angular intervals around the center of the bottom portion, spanning 360°. The strips of solid material of the bottom portion between two adjacent apertures are preferable narrow compared to the dimensions of the adjacent apertures so as to provide a mechanical support for the tablet electrode while also being able to deform under the influence of a volumetric expansion of the electrode.

    摘要： A secondary battery includes an outer package member and a battery device. The outer package member has a top part and a bottom part. The top part has a through hole extending in a first direction. The bottom part is disposed to be opposed to the top part in the first direction. The battery device is contained inside the outer package member. The battery device includes a stacked body. The stacked body includes a first electrode and a second electrode, and is wound around an internal space extending in the first direction. The battery device includes an outer wind part and an inner wind part. The outer wind part is sandwiched between the top part and the bottom part in the first direction. The inner wind part is located between the internal space and the outer wind part, and opposed to the through hole in the first direction.
