    • A secondary battery that can avoid reduction in battery capacity over the lapse of charge-discharge cycles and can exhibit high performance is provided. A method for manufacturing a secondary battery, the secondary battery including a laminated body having a pair of electrodes and an electrolyte layer provided between the pair of electrodes, the laminated body having an end portion, and a restrictor provided so as to cover at least the end portion of the laminated body for restricting expansion of the electrolyte layer in the plane direction thereof, the method includes preparing a mold, the pair of electrodes and electrolyte particles for forming the electrolyte layer, joining the pair of electrodes and the electrolyte layer together by pressing the electrodes and the electrolyte particles within the mold to form the laminated body, and providing the restrictor so as to cover at least the end portion of the laminated body removed from the mold.
    • 提供了能够避免在充放电循环过程中电池容量下降并且可以表现出高性能的二次电池。 一种二次电池的制造方法,所述二次电池包括具有一对电极的层叠体和设置在所述一对电极之间的电解质层,所述层叠体具有端部,所述限制器设置成至少覆盖所述电极 层叠体的端部,用于限制电解质层在其平面方向上的膨胀,该方法包括制备模具,用于形成电解质层的一对电极和电解质颗粒,将一对电极和电解质层一起接合在一起,由 将模具内的电极和电解质颗粒按压以形成层叠体,并且设置限制器以至少覆盖从模具移除的层压体的至少端部。
