1. A method for manufacturing a solid-state battery, comprising the steps of:
S1) applying a first electrolyte slurry to a surface of a first electrode to prepare a first electrode portion having a first electrolyte slurry layer formed on the surface thereof;
S2) applying a second electrolyte slurry to a surface of a second electrode to prepare a second electrode portion having a second electrolyte slurry layer formed on the surface thereof;
S3) binding the first electrode portion with the second electrode portion in such a manner that the first electrolyte slurry layer and the second electrolyte slurry layer face each other to obtain a product; and
S4) carrying out drying of the product of step S3),
wherein the solid-state battery comprises a positive electrode/solid electrolyte layer/negative electrode stacked successively, and
wherein step S3) is carried out immediately after steps S1) and S2) while maintaining the first electrolyte slurry and the second electrolyte slurry in a non-dried slurry state, and
wherein the first electrode and the second electrode are dried, and then pressed before applying the first electrolyte slurry and the second electrolyte slurry, respectively.
