摘要： An argyrodite-based solid electrolyte may contain a compound having a novel composition calculated by simulation of Ab initio molecular dynamics (AIMD). The solid electrolyte containing a compound having a novel composition that satisfies a certain range of monoatomic disorder (è) and a certain range of standard deviation (STD) of the size of the area formed as migration paths of Li metals, which are calculated by AIMD simulation, has an advantage of excellent ion conductivity due to promoted diffusion of monoatoms in the area.
