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. |
