    Abstract: 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.

    Abstract: A recovering process for recovering constituents of sealed battery comprises decreasing conductance between cathode and anode by cooling sealed battery with compressed incombustible gas comprising nitrogen gas, argon gas, helium gas, carbon dioxide gas, and/or fluorocarbon gas to a temperature lower than freezing point of solvent of electrolyte solution; and opening battery housing. A recovering process for recovering the constituents of a sealed battery comprising at least a cathode, an anode, and an electrolyte sealed in a battery housing between the cathode and the anode, comprising an electrolyte solution with a solvent, comprises decreasing the conductance between the cathode and the anode by cooling the sealed battery with a compressed incombustible gas comprising nitrogen gas, argon gas, helium gas, carbon dioxide gas, and/or fluorocarbon gas to a temperature lower than the freezing point of the solvent of the electrolyte solution; and opening the battery housing of the sealed battery. An independent claim is included for a recovering apparatus for recovering the constituents of a sealed battery as above, comprising mechanism(s) for sorting the sealed battery depending on the shape or the type, a cooling mechanism for decreasing the conductance between the cathode and the anode of the sealed battery, and a mechanism for opening the battery housing of the sealed battery. The cooling mechanism cools the sealed battery with a compressed incombustible gas comprising nitrogen gas, argon gas, helium gas, carbon dioxide gas, and/or fluorocarbon gas to a temperature lower than the freezing point of the solvent of the electrolyte solution.
