MANUFACTURING METHOD OF ALL-SOLID BATTERY
Document Type and Number:
Japanese Patent JP2021140892
Kind Code:
A
Abstract:
To provide a manufacturing method of an all-solid-state battery capable of appropriately stacking a plurality of battery units.SOLUTION: A manufacturing method of an all-solid-state battery includes a battery unit manufacturing step (S1), a shape regulation step (S2), and a laminating step (S4). In the battery unit manufacturing step, a plate-shaped battery unit is manufactured by undergoing a pressing step of pressing a laminate including at least one each of a positive electrode active material layer, a solid electrolyte, and a negative electrode active material layer in the thickness direction. In the shape regulation step, the battery unit is restricted to a predetermined curved shape by pressing the battery unit manufactured in the battery unit manufacturing step in the thickness direction in a state of being heated to temperature equal to or higher than temperature at which the battery unit softens and deforms. In the laminating step, the plurality of battery units regulated to have the same curved shape are laminated.SELECTED DRAWING: Figure 2
