Abstract:
1. A method for producing a solid electrolyte structure, the method comprising: a precursor preparation process of preparing a structure precursor; and a structure production process of sintering the structure precursor to produce the solid electrolyte structure; wherein the precursor preparation process comprises a first dispersing step of dispersing fine particles of a solid electrolyte in a solvent to form a first solution, a first depositing step of depositing a first layer containing aggregated fine particles of a solid electrolyte by drying the first solution, a second dispersing step of dispersing fine particles of the solid electrolyte in a solvent to form a second solution, and a second depositing step of depositing a second layer containing polymer particles and aggregated fine particles of the solid electrolyte by drying the second solution, wherein while the second solution is dried, the polymer particles are immersed therein; wherein the first solution is deposited on the second layer or the second solution is deposited on the first layer; and wherein the structure production process comprises a step of sintering the structure precursor, thereby removing the polymer particles to produce the solid electrolyte structure having a porous solid electrolyte portion and a dense solid electrolyte portion in an integrated state.
