  • Solid-state materials with extremely high ionic diffusion are necessary to many technologies including all-solid-state Li-ion batteries. In this work, we demonstrate through experimental characterization and theoretical analysis that LiTi2(PS4)3 or LTPS shows exceptional Li-ion diffusion, an order of magnitude higher than current state-of-the-art superionic conductors. We propose a rationalization to this behavior by the frustrated energy landscape experienced by lithium ions in the LTPS… CONTINUE READING
