A method for manufacturing a multilayer electronic component having an element body in which a functional part and a conductor part are laminated. The green multilayer body 11 is formed on the temporary holding film 62 formed on the release substrate. The green multilayer body 11 is formed by repeating the first step forming a green functional part using the first ink containing the functional particles and the second step forming the green conductor part using the second ink containing the conductive particles. The temporary holding film 62 has conductivity.

The disclosure herein relates to rechargeable batteries and solid electrolytes therefore which include lithium-stuffed garnet oxides, for example, in a thin film, pellet, or monolith format wherein the density of defects at a surface or surfaces of the solid electrolyte is less than the density of defects in the bulk. In certain disclosed embodiments, the solid-state anolyte, electrolyte, and catholyte thin films, separators, and monoliths consist essentially of an oxide that conducts Li.sup.+ ions. In some examples, the disclosure herein presents new and useful solid electrolytes for solid-state or partially solid-state batteries. In some examples, the disclosure presents new lithium-stuffed garnet solid electrolytes and rechargeable batteries which include these electrolytes as separators between a cathode and a lithium metal anode.
