Abstract：
Solid-state  batteries  have  seen  a  resurgence  of  interest  in  recent  years, because  of  their  potential for  enhanced  safety  and  energy  density.  However,  major obstacles of implementing solid-state batteries  on both material and  system  levels  are challenging  to  be  overcome.  In  this  talk,  taking  sodium  solid-state batteries as an example,  I  will  discuss  how  the  application  of  advanced  scattering  and  spectroscopy techniques  together  with  ab  initio  modeling  identifies  important  factors  that  determine solid-state  battery  interface  stabilities,  and  how  these 
scientific  insights  can  lead  to integration  criteria  of  solid-state battery components.  In specific,  the key  to enable Naion  conductivity for a class of emerging  Na solid-state  electrolytes (i.e., Na3PX4, X = S,Se)  will  be  discussed.  The  different  decomposition  pathways  of  the  solid-state electrolyte  and  at  the  interfaces  of  electrolyte/electrode  and  electrolyte/carbon  will  be also  discussed.  We  distinguish  the  thermodynamic  and  kinetic  stabilities  of  the electrolyte,  providing  more  precise  insights  into  the  competition  between thermodynamics and kinetics in solid-state electrolyte decompositions.
