SC1-500P
For teams evaluating argyrodite sulfide electrolytes, the decision usually comes down to three questions: does the composition match our target conductivity, is the particle size appropriate for our cell architecture, and can the supplier deliver consistent material from evaluation quantities through to pilot-scale procurement? This guide walks through each question in turn, with direct links to the corresponding SKU on our product page.
The Complete Grade Matrix
All nine Xnergy LPSCl grades share the same theoretical density (2 g/cm³), moisture specification (< 500 ppm), electronic conductivity ceiling (< 1 × 10⁻⁸ S/cm at 27 °C), and phase-purity requirement (clean Li-argyrodite primary phase, no detectable Li2S). They differ in composition and primary particle size, which together determine the achievable ionic conductivity. Each SKU below links directly to its position on our product page.

Ionic conductivity measured by EIS on cold-pressed pellets (6-ton laboratory press) at 27 °C. Electronic conductivity verified < 1 × 10⁻⁸ S/cm for all grades.
The Three Series, Explained
SC2 Series — Halogen-rich Argyrodite
FlagshipLi5.5PS4.5Cl1.5
The SC2 series is built on a chloride-enriched argyrodite lattice. Extra anion disorder on the Cl sites opens additional Li-ion transport channels, pushing room-temperature conductivity into the 5–10 mS/cm range — the highest of the three families. SC2-05UP sits at the top of the commercially available argyrodite conductivity spectrum at > 10 mS/cm, making it Xnergy's flagship grade for separator-layer applications where bulk transport is the limiting factor.
- Maximum achievable ionic conductivity for a sulfide electrolyte
- Best-in-class separator or electrolyte-pellet performance
- High-rate cell demonstrations where ionic bottlenecks dominate
SC1 Series — Dual-Halogen Argyrodite
Advanced ResearchLi5.5PS4.5(Cl,Br)1.5
The SC1 series is a halogen-rich argyrodite in which part of the chloride is substituted with bromide. The larger Br⁻ anion further disrupts the lattice and alters grain-boundary chemistry, relevant for groups studying interfacial stability, electrode–electrolyte compatibility, and advanced halide engineering. SC1-500P is the only Xnergy grade that extends down to < 0.5 μm for thin-film and slurry-cast applications.
- Halogen-engineered argyrodite for interface or grain-boundary research
- A commercial alternative to in-house Br-doped synthesis
- Sub-micron or ultra-fine powder for composite cathode or slurry-cast membrane work
SC0 Series — Classical Li6PS5Cl
Literature BenchmarkLi6PS5Cl
The SC0 series is the literature-standard composition: Li6PS5Cl, the argyrodite that appears in the majority of published benchmarking studies. If you need reproducibility against the published record — for peer review, for method validation, for teaching purposes — this is the composition to specify. The SC0 series covers the full particle-size range from > 5 μm down to < 1 μm, giving you a matched set of grades for every position in the cell.
- Direct comparability with published Li6PS5Cl literature
- A reliable baseline for new cell architectures or cathode materials
- A cost-effective sulfide electrolyte for routine evaluation work
How to Choose Your Grade
Two questions lead you to the right SKU: what is the application, and what composition does your study require? The matrix below cross-references both. Every cell links to the corresponding product page.
| If your application is… | Classical (SC0) | Halogen-rich (SC2) | Dual-halogen (SC1) |
|---|---|---|---|
| Separator / electrolyte pellet | SC0-05UP | SC2-05UP ★ | — |
| General research / benchmarking | SC0-03UP | SC2-03UP | SC1-03UP |
| Composite cathode / catholyte | SC0-01UP | SC2-01UP | SC1-01UP |
| Thin-film / slurry-cast membrane | — | — | SC1-500P ★ |
★ indicates the recommended grade for each application.
Quality Control & Analytical Methods
Every Xnergy LPSCl lot is characterized with the same analytical suite, with results reported on the Certificate of Analysis (CoA) that accompanies every shipment:
Handling, Packaging & Shipping
Every order is supplied in vacuum-sealed glass vials under argon, in packaging suitable for direct glove-box transfer. Shelf life is one year from the date of manufacture when containers remain sealed under inert atmosphere.
Standard research quantities: 10 g, 25 g, 50 g, 1 kg. Custom larger quantities available for pilot-scale programs on request.
All international shipments are classified as hazardous material and ship with the required packaging, documentation, and carrier certifications. Please allow additional lead time for hazmat processing relative to standard chemical shipments.
How to Order
Three paths depending on where you are in your evaluation:
Request a Sample
For first-time technical evaluation. Specify your target grade and intended application.
Request Datasheet
Full specifications, test conditions, and analytical methods for any of the nine grades.
Bulk Quotation
For pilot-line or production-scale procurement. Tell us your target volume and delivery schedule.
Quick Recommendation
Not sure where to start? For most first-time orders, one of these three SKUs will cover your needs:
→ Maximum conductivity, separator work: SC2-05UP (> 10 mS/cm)
→ Literature benchmark, balanced: SC0-03UP (Li6PS5Cl, 3.0 ± 0.5 μm)
→ Thin-film / advanced interface work: SC1-500P (dual-halogen, < 0.5 μm)
