Title:
LAMINATED ALL-SOLID SECONDARY CELL AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2020/184652
Kind Code:
A1
Abstract:
Provided is a laminated solid secondary cell, including: a laminate, in which a positive electrode (30, 330) having a positive electrode collector layer (31, 331) and a positive electrode active material layer (32, 332), and a negative electrode (40, 340) having a negative electrode collector layer (41, 341) and a negative electrode active material layer (42, 342), are laminated with a solid electrolyte layer (50, 350) interposed therebetween, the laminate having side surfaces formed as surfaces parallel to the lamination direction, the side surfaces including a first side surface (21, 121, 321) on which the positive electrode collector layer (31, 331) is exposed and a second side surface (22, 122, 322) on which the negative electrode collector layer (41, 341) is exposed; a positive electrode external electrode (60, 61, 62, 63, 64, 365) attached to the first side surface (21, 121, 321); and a negative electrode external electrode (70, 71, 72, 73, 74, 375) attached to the second side surface (22, 122, 322). The positive electrode external electrode (60, 61, 62, 63, 64, 365) is connected to the positive electrode collector layer (31, 331). The side end part of the positive electrode external electrode (60, 61, 62, 63, 64, 365) is located at a position that does not face the negative electrode (40, 340). The negative electrode external electrode (70, 71, 72, 73, 74, 375) is electrically connected to the negative electrode collector layer (41, 341). The side end part of the negative electrode external electrode (70, 71, 72, 73, 74, 375) is located at a position that does not face the positive electrode (30, 330).
