Method for manufacturing all-solid-state battery

A method for manufacturing an all-solid-state battery, comprising steps of:

• (1) providing an all-solid-state electrolyte layer sheet;
• (2) compartmentalizing the all-solid-state electrolyte layer sheet to accommodate two electrodes disposed apart from each other in a width direction and two or more pairs of electrodes disposed apart from each other in a longitudinal direction;
• (3) laminating first electrodes having a first polarity on a front side of the compartmented all-solid-state electrolyte layer sheet in a zigzag pattern,
• wherein the step (3) is performed by selecting one of a plurality of compartment unit groups connected in a diagonal direction among compartment units compartmentalized on the front side of the all-solid-state electrolyte layer sheet, and then laminating the first electrodes having the first polarity;
• (4) laminating second electrodes having a second polarity different from the first polarity on a rear side of the compartmented all-solid-state electrolyte layer sheet on which the first electrodes having the first polarity are not laminated on the front side;
• and
• (5) folding and stacking the all-solid-state electrolyte layer sheets in which the first and second electrodes are laminated so that each of the first electrodes and each of the second electrodes are stacked in turn in a state without contacting with each other.
