조성이 가넷 Li-함유 고체 전해질과 동일하거나, 실질적으로 유사한 Li-함유 가넷 물질로부터 세터 플레이트를 제조한다. 본원에 기술된 Li-함유 가넷 세터 플레이트는 소결 처리 단계 동안 Li의 증발을 감소시키고/거나, 소결 전해질 밖으로의 확산에 의해 유발되는 Li 손실을 감소시킨다. 본원에 기술된 Li-함유 가넷 세터 플레이트는 가열시, 리튬이 고체 전해질 밖으로 확산되는 경향이 있을 때, 소결 동안 고체 전해질에 대한 조성 조절을 유지한다. Setter plates are fabricated from Li-stuffed garnet materials having the same, or substantially similar, compositions as a garnet Li-stuffed solid electrolyte. The Li-stuffed garnet setter plates, set forth herein, reduce the evaporation of Li during a sintering treatment step and/or reduce the loss of Li caused by diffusion out of the sintering electrolyte. Li-stuffed garnet setter plates, set forth herein, maintain compositional control over the solid electrolyte during sintering when, upon heating, lithium is prone to diffuse out of the solid electrolyte.
