Elucidation of ion dynamics in Li3PS4 solid electrolytes for all solid state batteries by means of inelastic neutron scattering
All-solid-state batteries are one of the main contenders for the batteries of the future due to their potential advantages in terms of safety, cycle-life and energy density. Li3PS4 has emerged as one of the candidate solid electrolyte materials at the heart of the solid-state battery concept. Nevertheless, the reasons for its high ionic conductivity and its variance depending on the synthesis method are poorly understood. We have synthesized Li3PS4 utilizing all the prominent synthesis routes in the literature (ceramic, quenching, mechanochemical, soft-chemistry) and propose to perform a comprehensive series of inelastic neutron scattering experiments to elucidate the dynamical effects of atomic structure, microstructure and composition as pertains to Li ion transport in Li3PS4.
