The object of the present invention is to provide a secondary battery that has a lamination of negative electrodes and positive electrodes with intervening separators that acquires a low battery internal impedance and excellent charging and discharging power by the sufficient compressing of the electrodes, and that is very safe and easy to recycle, and to provide a method for manufacturing such a battery. To achieve the above object, according to the present invention, in a battery wherein positive electrodes and negative electrodes are disposed with intervening separators, and are stored in a battery case with a solid electrolyte or an electrolytic solution, provided in the battery case is a member whose shape is changed at a predetermined temperature (first temperature), which is lower than the melting point of the separator and which falls outside the battery operating temperature range, that maintains the shape in the battery operating temperature range. By heating or cooling the member to the first temperature, pressure is applied to at least one part of the battery case or the applied pressure is released. <MATH> |
