Impact of intentional composition tuning on the sintering properties of Ca–Bi co-doped Li7La3Zr2O12 for co-fired solid-state batteries

Ca and Bi co-doped Li 7 La 3 Zr 2 O 12 electrolytes exhibiting 1.2 × 10 −3 S cm −1 at 750 °C sintering are realized by combining the Li–Bi–O sintering aid. A co-fired all-solid-state battery fabricated using this material achieves 80 cycles.
