Engineering Frenkel defects of anti-perovskite solid-state electrolytes and their applications in all-solid-state lithium-ion batteries

Fluorinated lithium-rich anti-perovskite (F-LiRAP) is proposed to enhance lithium ion conductivity by creating Frenkel defects that facilitate the formation of lithium-rich and lithium-vacancy couples. We successfully demonstrate an all-solid-state cell configuration based on F-LiRAP, precluding the employment of polymer or liquid additives.
