Method for producing solid electrolyte structure, method for producing all-solid-state-cell, solid electrolyte structure, and all-solid-state-cell

摘要

A first fine particle-containing solution (12) is deposited on an appropriate substrate (10), and dried to form a first fine particle aggregate layer (14). Polymer particles (16) are deposited on the first fine particle aggregate layer (14), and are supplied with a second fine particle-containing solution (18) such that the polymer particles (16) are immersed in the second fine particle-containing solution (18). The second fine particle-containing solution (18) is dried to form a second fine particle aggregate layer (20) containing a large number of the polymer particles (16) embedded. A first structure precursor (22) is completed at this stage. Then, the first structure precursor (22) is separated from the substrate (10), and thermally treated. Thus, the production of a first solid electrolyte structure (24), which has a porous solid electrolyte portion (28) and a dense solid electrolyte portion (30) integrated, is completed.
