LGPS has since garnered substantial attention, both for elucidating its underlying mechanisms and addressing cost-related concerns. The LGPS material features (Ge 0.5 P 0.5 )S 4 tetrahedra and PS 4 tetrahedra with space group P4 2 /nmc, as illustrated in Fig. (d). Li + ions occupy tetrahedral and octahedral sites, allowing for one-dimensional Li + diffusion along the crystallographic c-axis , as depicted in Fig. .
