Al-Doped LZC is a halide-class solid-state electrolyte derived from Li2ZrCl6 with aluminum substitution at the Zr site. The doping enhances room-temperature ionic conductivity to 0.6–0.8 mS/cm while preserving halide chemistry’s intrinsic stability against high-voltage cathodes — enabling all-solid-state lithium battery (ASSLB) operation without cathode interface coatings.

Catholyte for all-solid-state lithium batteries. Suitable for sulfide-halide composite electrolyte architectures (paired with LPSC or LGPS as anode-side separator), high-voltage cathodes (LCO, NCM/Ni83), and solid-state pouch cell prototyping.
Vacuum-sealed under inert atmosphere in moisture-barrier aluminum-laminated bags. Store sealed in Ar or N2 glovebox. LZC is moisture-sensitive — handle in dry environment with dew point < –40 °C. Reseal promptly after opening.
For research and industrial use only. Wear appropriate PPE (chemical-resistant gloves, dust mask or respirator, safety goggles, lab coat). Handle in a glovebox or fume hood under inert atmosphere. Avoid contact with moisture, water, and incompatible materials. Refer to the included Safety Data Sheet (SDS) for complete safety and handling information.

This material is moisture-sensitive and must be stored in an inert atmosphere. Handle only in a glovebox or fume hood with dew point below -40°C to prevent degradation.
- Moisture Sensitivity: Exposure to moisture degrades the ionic conductivity of the electrolyte.
- Storage Atmosphere: Store sealed in an argon or nitrogen glovebox to maintain inert conditions.
- Handling Environment: Handle in a dry environment with dew point below -40°C to avoid moisture absorption.
- Post-Use Sealing: Reseal the moisture-barrier bag promptly after each use to limit exposure.
This procedure describes safe handling and storage of the moisture-sensitive electrolyte powder. Follow these steps to maintain material integrity and prevent contamination.
Required Equipment: Argon-filled glovebox
- Transfer to glovebox
Place the sealed moisture-barrier bag into an argon-filled glovebox with dew point below -40°C. - Open bag
Open the vacuum-sealed bag only inside the glovebox to prevent moisture contamination. - Remove powder
Remove the desired quantity of electrolyte powder from the open bag using a clean instrument. - Reseal bag
Reseal the bag immediately after removing the powder to limit moisture exposure.
How does Al doping improve the ionic conductivity of LZC halide solid-state electrolyte?
Al substitution at the Zr site in Li2ZrCl6 enhances room-temperature ionic conductivity to 0.6–0.8 mS/cm (typical 0.7 mS/cm at 28 °C), as measured by EIS on a 1.2 mm pellet. This doping preserves the Li2ZrCl6 crystal structure confirmed by XRD while increasing conductivity relative to the undoped LZC baseline.
Can Al-doped LZC be used with sulfide solid electrolytes like LPSC or LGPS in composite electrolyte architectures?
Yes, the product is designed for sulfide-halide composite electrolyte architectures where it serves as a catholyte paired with LPSC or LGPS as the anode-side separator. This configuration enables all-solid-state lithium battery operation with high-voltage cathodes such as LCO and NCM without requiring cathode interface coatings.
What are the storage and handling requirements for Al-doped LZC halide solid-state electrolyte?
The material is moisture-sensitive and supplied vacuum-sealed in moisture-barrier aluminum-laminated bags under inert atmosphere. It must be stored and handled in an Ar or N2 glovebox with a dew point below –40 °C. After opening, reseal promptly and always wear appropriate PPE including chemical-resistant gloves, dust mask, safety goggles, and a lab coat.
Al-Doped LZC (Li2.25Zr0.75Cl6Al0.25) is a halide solid-state electrolyte with Al doping enhancing room-temperature ionic conductivity to 0.6–0.8 mS/cm. Its intrinsic stability against high-voltage cathodes (e.g., LCO, NCM) eliminates the need for cathode interface coatings in all-solid-state lithium batteries.
Positive
- High-voltage cathode compatibility: The halide chemistry provides intrinsic electrochemical stability against 4V-class cathodes, enabling operation without protective interface coatings, reducing fabrication complexity.
- Enhanced ionic conductivity: Al doping at the Zr site increases room-temperature ionic conductivity to 0.6–0.8 mS/cm (typical 0.7 mS/cm at 28°C), improving rate capability in solid-state cells.
Trade-offs
- Moisture-sensitive handling required: LZC is moisture-sensitive and must be handled in a dry environment with dew point below -40°C, stored in Ar or N2 glovebox, increasing infrastructure and handling costs.
- Pellet testing condition caveat: Conductivity is measured under EIS on a 1.2 mm pellet at 28°C; performance in full-cell or thin-film architectures may vary and requires application-specific validation.
