摘要: Dynamic lithium distribution, structural stability and ion transport mechanism in the new ultrafast conductor Li10GeP2S12 are clarified with help of atomistic molecular dynamics simulations, revealing only a weak anisotropy Li+ diffusion, coupling cation diffusion to PS43− anion rotational mobility. The role previously overlooked Li site limited at elevated temperatures discussed for first time.
