Patent ID: 8870976

Claim:
A method for manufacturing a secondary battery, comprising: preparing a mold, a pair of electrodes, and electrolyte particles; forming a laminated body by providing one of the pair of electrodes into the mold, providing the electrolyte particles into the mold so as to lie onto the electrode, pressing the electrolyte particles so that the electrolyte layer is formed and the electrode and the electrolyte layer are joined together, providing the other electrode into the mold so as to lie onto the electrolyte layer, and pressing the electrodes in the mold so as to come close to each other so that the pair of electrodes and the electrolyte layer are joined together; providing a restrictor so as to cover and seal at least an end portion of the laminated body that is removed from the mold, the restrictor being made of an insulating material containing at least one of P 2 O 5 —CuO—ZnO-based glass, P 2 O 5 —SnO-based glass and B 2 O 3 —ZnO—Bi 2 O 3 —Al 2 O 3 -based glass; wherein providing the restrictor is started immediately after release of a pressure applied in pressing the electrodes, a time taken from the pressure release to initiation of providing the restrictor is equal to or shorter than 300 minutes; wherein when an average thickness of the laminated body immediately after pressing the electrodes is defined as A (μm) and an average thickness of the laminated body immediately before providing the restrictor is defined as B (μm), a relationship A/B is equal to or greater than 0.95.
