LPSCL‑Br (Li5.4PS4.4ClBr0.6) Sulfide Solid‑State Electrolyte Powder is designed for all-solid-state lithium battery research and prototype production. With superior lithium-ion conductivity, it can be uniformly blended with mainstream cathode materials like NCM, LCO and LNMO to build continuous ion transport pathways and lower interfacial resistance. It can be cold-pressed into dense pellets to replace traditional liquid electrolytes and separators, suitable for coin cell and pouch cell assembly, interface optimization and long-cycle performance research. Additionally, it can be compounded with polymers to fabricate flexible composite electrolyte films for enhanced mechanical stability and battery flexibility.

This sulfide solid-state electrolyte powder is highly moisture-sensitive and releases toxic sulfur-containing gas upon hydrolysis. Storage requires argon-filled vacuum-sealed packaging in a cool-dry environment, and all handling must be performed inside an inert atmosphere glovebox.
- Moisture Sensitivity: The powder hydrolyzes rapidly upon exposure to ambient moisture, generating toxic hydrogen sulfide gas.
- Glovebox Requirement: All opening, sampling, and processing steps must be conducted inside an argon-filled glovebox to maintain an anhydrous atmosphere.
- Storage Conditions: Store the sealed package in a cool, dry location away from direct sunlight and heat sources.
- Prompt Use After Opening: Once opened, use the powder immediately and reseal the container to limit air exposure and prevent moisture ingress.
This guide describes the safe handling procedure for the moisture-sensitive sulfide electrolyte powder. All steps must be performed under argon atmosphere in a glovebox to prevent exposure to air and moisture.
Required Equipment: Argon-filled glovebox
- Inspect packaging
Inspect the vacuum-sealed packaging for any damage or leakage before opening. - Transfer to glovebox
Transfer the sealed package into an argon-filled glovebox with controlled atmosphere. - Open package
Open the package only inside the glovebox to prevent moisture exposure. - Use promptly and reseal
Use the powder promptly after opening and reseal the container to minimize air exposure.
What is the ionic conductivity of LPSCL‑Br sulfide solid electrolyte and what cold-pressing conditions are required to achieve it?
LPSCL‑Br (Li5.4PS4.4ClBr0.6) exhibits an ionic conductivity of ≥5 mS/cm at 25°C under a cold-pressing pressure of 300 MPa. The powder has a particle size of 1.5–3.0 µm, which supports dense pellet formation for all-solid-state battery assembly.
Which cathode materials are compatible with LPSCL‑Br for all-solid-state batteries?
LPSCL‑Br is blendable with NCM, LCO, and LNMO cathode materials. It builds continuous lithium-ion transport networks and reduces interfacial resistance, making it suitable for composite cathode preparation in all-solid-state lithium batteries.
How should LPSCL‑Br sulfide electrolyte be stored and handled to prevent degradation?
LPSCL‑Br must be stored in an argon-filled vacuum-sealed package in a cool, dry environment. It is highly moisture-sensitive and releases toxic sulfur-containing gas upon hydrolysis. All handling and sampling should be performed in a glovebox, and the material should be used promptly after opening to avoid air exposure.
LPSCL‑Br (Li5.4PS4.4ClBr0.6) sulfide solid-state electrolyte powder delivers ≥5 mS/cm ionic conductivity at 25°C and 300 MPa, and blends effectively with NCM, LCO, and LNMO cathodes to reduce interfacial resistance, but requires strict moisture-free handling in gloveboxes due to hydrolysis and toxic gas release.
Positive
- High lithium-ion conductivity: Ionic conductivity ≥5 mS/cm at 25°C and 300 MPa enables efficient ion transport in all-solid-state batteries, supporting high-rate and long-cycle performance.
- Cathode compatibility for low interfacial resistance: Blends uniformly with NCM, LCO, and LNMO cathodes to build continuous ion pathways and reduce interfacial resistance, critical for composite cathode performance.
Trade-offs
- Extreme moisture sensitivity: Highly reactive with moisture, releasing toxic sulfur-containing gases upon hydrolysis; requires argon-filled vacuum-sealed storage and glovebox handling for all sampling and processing.
- Limited air exposure tolerance after opening: Must be used promptly after opening and kept sealed in a cool, dry environment; any air exposure degrades performance and poses safety risks.
