Publication number: 20220416310Abstract: A method for manufacturing a laminated battery is a method for manufacturing a laminated battery in which a plurality of unit battery cells each having a negative-electrode layer, a positive-electrode layer are laminated, and a solid electrolyte layer located between the negative-electrode layer and the positive-electrode layer. The method includes laminating the plurality of unit battery cells and collectively compressing, in a direction of laminating, the plurality of unit cells laminated in the laminating. In the laminating, the plurality of unit battery cells are laminated in such an arrangement that two unit battery cells located at both ends in the direction of laminating are both lower in degree of compression than a unit battery cell located between the two unit battery cells.Type: ApplicationFiled: September 6, 2022Publication date: December 29, 2022Inventors: KAZUYOSHI HONDA, AKIRA KAWASE, EIICHI KOGA, TSUTOMU KOSHIZUKA, TAKESHI YAMASAKI, MASATOSHI NAKAMURA
