Technical Selection Guide

How should Li5.5PS4.5Cl1.5, D50 2.168 um be selected and tested?

Li5.5PS4.5Cl1.5, D50 2.168 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.

Why developers evaluate it

  • Cold-pressed pellet and conductivity screening
  • Composite-cathode contact and percolation studies
  • Lithium-metal interface and pressure-dependence testing

Development considerations

  • Use dry, inert handling and appropriate safety controls
  • Report pellet pressure, density, thickness, and temperature
  • Evaluate electronic conductivity, impurities, and interfacial stability

How to compare it

This grade should be compared with other particle-size variants under identical pressing and EIS conditions. Listed parameters include Particle size: D10 0.567 um; D50 2.168 um; D90 6.592 um; Electronic: 1.38 x 10^-6 mS/cm; Ionic: 8.5 mS/cm, cold press. Higher conductivity in a pellet does not by itself establish better composite-electrode or full-cell performance.
