Technical Selection Guide
Li5.5PS4.5Cl1.5, D50 >10 um is a sulfide solid electrolyte grade for pressed-pellet, composite-cathode, and lithium-metal interface research. Sulfide powders can provide high ionic conductivity and cold-press densification, but measured performance depends on particle-size distribution, pressure, density, moisture exposure, phase purity, and electrode contact.
This grade should be compared with other particle-size variants under identical pressing and EIS conditions. Listed parameters include Particle size: D50 >10 um; Electronic: <= 10^-6 mS/cm; Ionic: >10 mS/cm, cold press. Higher conductivity in a pellet does not by itself establish better composite-electrode or full-cell performance.
