Abstract
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.
