Technical Selection Guide
Li5.5PS4.5ClxBr1.5-x, D50 0.759 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: D10 0.427 um; D50 0.759 um; D90 1.277 um; Electronic: 2.37 x 10^-6 mS/cm; Ionic: 6.5 mS/cm, cold press. Higher conductivity in a pellet does not by itself establish better composite-electrode or full-cell performance.
