Sulfide solid electrolytes (such as Although $Li_{6}PS_{5}Cl$ exhibits outstanding ionic conductivity, its extremely high sensitivity to moisture and oxygen, as well as its tendency to form hard agglomerates after sintering, have long posed significant challenges in its fabrication.
The vortex-ring mill generates a highly precise and controllable flow field within a sealed chamber by simulating the ultra-high-speed vortex airflow of a tornado. As a leading particle-disaggregation device in the industry, it enables particles to undergo self-grinding and shear within the entrained gas stream, effectively breaking up hard agglomerates.
This equipment serves not only as a pulverizing tool but also as a highly efficient activation device. During the pulverization process, high-energy physical collisions instantly break through the surface oxide layer, exposing active crystal facets. As a result, the particle size distribution of the treated material is significantly improved. At 40%, the ionic conductivity remains stably above $10^{-3} \\, \\text{S/cm}$, significantly reducing the solid–solid interfacial impedance.
