GREEN SHEET, LAMINATE GREEN SHEET, CONTINUOUS LAMINATE GREEN SHEET, ALL-SOLID TYPE SECONDARY BATTERY, AND FABRICATION METHODS THEREOF

摘要

PROBLEM TO BE SOLVED: To provide: a laminate green sheet which can make contribution to the enhancement in the performance of an all-solid type secondary battery, which enables the simplification of its fabrication process, and which allows the interface resistance of each layer to be kept down; an all-solid type secondary battery arranged by use of the laminate green sheet; and fabrication methods thereof.SOLUTION: A laminate green sheet is manufactured by the steps of: adding a material, which is thermally decomposed to form cavities when baked, to a slurry for making one or more kinds of electrode layers; and using the resultant slurry to laminate, on a first current collector, a first electrode layer green sheet, a solid electrolyte layer green sheet and a second electrode layer green sheet in this order. An all-solid type secondary battery is manufactured by putting together a second current collector on the second electrode layer green sheet of the laminate green sheet, followed by collective baking. A series all-solid type secondary battery is manufactured by collectively baking a continuous laminate green sheet manufactured by successively laminating laminate green sheets identical to the above laminate green sheet.SELECTED DRAWING: Figure 1
