Title:
LAMINATE TYPE ALL-SOLID BATTERY AND MANUFACTURING METHOD THEREOF
Document Type and Number:
Japanese Patent JP2018181451
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a laminate type all-solid battery having a high battery performance (e.g. output and cycle life characteristics), and a method for manufacturing the laminate type all-solid battery.SOLUTION: A laminate type all-solid battery 200 is arranged by laminating a plurality of all-solid batteries 100 each comprising: a positive electrode layer 10 having a positive electrode current collector 11, and a positive electrode active material layer 13 formed on the positive electrode current collector 11 and including a positive electrode active material 12; a negative electrode layer 20 having a negative electrode current collector 21, and a negative electrode active material layer 23 formed on the negative electrode current collector 21 and including a negative electrode active material 22; and a solid electrolyte layer 30 disposed between the positive electrode active material layer 13 and the negative electrode active material layer 23, and including a solid electrolyte 31 having lithium ion conductivity. As to two adjacent all-solid batteries 100a and 100b of the plurality of all-solid batteries 100a to 100f, the positive electrode current collector 11 of one all-solid battery 100b is directly joined to the negative electrode current collector 21 of the other all-solid battery 100a. The laminate type all-solid battery has a cavity 40 at a joining interface between the one all-solid battery 100b and the other all-solid battery 100a.SELECTED DRAWING: Figure 1
