Abstract: The present application provides a composite solid state electrolyte slurry, a film, a preparation method, and an all solid state battery. The method includes: adding a polymer into a non-polar solvent and mixing the polymer and the non-polar solvent to obtain a sol; adding a solid state electrolyte powder and a lithium salt solution into the sol and mixing the solid state electrolyte powder, the lithium salt solution and the sol to obtain a composite solid state electrolyte slurry; the non-polar solvent is an organic solvent that does not react with the solid state electrolyte powder; the high shear force of the sol is used to disperse the solid state electrolyte powder and lithium salt solution, thereby the solid state electrolyte powder and the lithium salt solution are uniformly dispersed in the sol.

Abstract: The present application provides a solid state electrolyte, a preparation method thereof, and an all solid state battery. Multi-element co-doping of lithium-rich, sodium-rich, potassium-rich anti-perovskite electrolytes on lithium sites or sodium sites or potassium sites, oxygen sites and halogen sites effectively improves the ionic conductivity of the anti-perovskite solid state electrolyte.
