Technical Selection Guide
Li5.5PS4.5ClxBr1.5-x, D50 2.398 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 0.623 um; D50 2.398 um; D90 6.559 um; Electronic: 1.84 x 10^-6 mS/cm; Ionic: 9.2 mS/cm, cold press. Higher conductivity in a pellet does not by itself establish better composite-electrode or full-cell performance.
