Solid electrolyte with sulfide particles and lithium-metal-oxide coating
A newly filed patent (Publication Number: US20240039041A1) describes a solid electrolyte composed of sulfide-based solid electrolyte particles with lithium-metal-oxide on their surfaces. The solid electrolyte exhibits a specific X-ray diffraction analysis characteristic, with a full width at half maximum of a main peak less than or equal to about 0.160. The lithium-metal-oxide component includes elements such as Al, B, Ca, Ce, Cr, Fe, Mg, Mo, Nb, Si, Sn, Sr, Ta, V, W, and Zr, with a content ranging from about 0.01 wt % to about 3 wt % of the solid electrolyte.
The patent also details a method for preparing the solid electrolyte, involving mixing sulfide-based solid electrolyte particles and lithium-metal-oxide, followed by heat treatment at temperatures between about 250°C to 350°C. The process includes specific parameters such as the amount of lithium-metal-oxide to be mixed, the particle size distribution of the solid electrolyte, and the use of argyrodite-type sulfide in the composition. Additionally, the method includes steps like mixing and heat-treating sulfur-containing raw materials to obtain the desired sulfide-based solid electrolyte particles. The resulting solid electrolyte from this method also exhibits the characteristic X-ray diffraction analysis feature with a full width at half maximum of a main peak less than or equal to about 0.160.
