论文摘要
Solid-state electrolyte materials enable high energy density and safety for lithium ion batteries. High ionic conductivity is the first concern for the practical application of solid-state electrolyte. So, developing superionic conductors with high ionic conductivities and understanding fast ion diffusion are quite impending. We designed a series of LiMS2 with lithium-anion tetrahedrons and Li3MI6 with lithium-anion octahedra, and found lithium ion migration significantly affected by the choice of M element. The anion framework models are constructed to study the effects of anion charge on lithium ion migration, and new design principles for developing superionic conductors were proposed.
