Fabrication of Oxide-Based All-Solid-State Batteries by a Sintering Process Based on Function Sharing of Solid Electrolytes.

ABSTRACT: Garnet-type Li₇La₃Zr₂O₁₂ (LLZ) has advantages of stability with Li metal and high Li⁺ ionic conductivity, achieving 1 × 10^-3 S cm^-1, but it is prone to react with electrode active materials during the sintering process. LISICON-type Li_3.5Ge_0.5V_0.5O₄ (LGVO) has the advantage of less reactivity with the electrode active material during the sintering process, but its ionic conductivity is on the order of 10^-5 S cm^-1. In this study, these two solid electrolytes are combined as a multilayer solid electrolyte sheet, where 2 μm thick LGVO films are coated on LLZ sheets to utilize the advantages of these two solid electrolytes. These two solid electrolytes
