LZCO (Li2ZrOCl4) is a halide-oxide hybrid solid-state electrolyte engineered for next-generation all-solid-state lithium batteries (ASSLBs). The incorporation of oxygen into the Li2ZrCl6 framework dramatically enhances room-temperature ionic conductivity to 1.2–1.6 mS/cm — approaching sulfide-class performance while preserving halide chemistry’s intrinsic stability against high-voltage cathodes.

High-conductivity 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), high-power solid-state cells, pouch cell prototyping, and pilot-scale ASSLB manufacturing.
Vacuum-sealed under inert atmosphere in moisture-barrier aluminum-laminated bags. Store sealed in Ar or N2 glovebox. LZCO is moisture-sensitive — handle in dry environment with dew point < –40 °C. Reseal promptly after opening.
For research and industrial use only. Wear PPE (gloves, masks, safety goggles). Refer to SDS for complete safety information.

This material is moisture-sensitive and must be handled exclusively in a dry environment with dew point below –40 °C. Storage requires vacuum-sealed inert atmosphere packaging and residence in an argon or nitrogen glovebox to prevent degradation.
- Moisture Sensitivity: Exposure to atmospheric moisture degrades ionic conductivity and structural integrity.
- Dry Environment Requirement: All handling must be performed in a glovebox with dew point below –40 °C.
- Inert Atmosphere Storage: Store sealed in argon or nitrogen atmosphere to avoid moisture and oxygen exposure.
- Reseal After Opening: Reseal the vacuum-sealed bag immediately after each use to maintain inert conditions.
- Cathode Compatibility: Material is stable against 4 V-class cathodes but requires compatibility testing with specific cathode chemistries.
How does the ionic conductivity of LZCO (Li2ZrOCl4) compare to sulfide solid electrolytes, and what trade-off in cathode stability does it offer?
LZCO achieves ionic conductivity of 1.2–1.6 mS/cm (typical 1.55 mS/cm at 28 °C), approaching sulfide-class performance, but retains the intrinsic stability of halide chemistry against high-voltage cathodes such as LCO and NCM, unlike sulfides that are incompatible with oxide cathodes. This makes it suitable as a catholyte in all-solid-state batteries where both high conductivity and oxidative stability are required.
Can LZCO be used in composite electrolyte architectures with sulfide electrolytes like LPSC or LGPS?
Yes, LZCO is explicitly designed for sulfide-halide composite electrolyte architectures, where it can be paired with LPSC or LGPS as an anode-side separator. This configuration leverages LZCO's high-voltage stability on the cathode side while sulfides provide lithium-metal compatibility on the anode side.
What are the storage and handling requirements for LZCO due to its moisture sensitivity?
LZCO is moisture-sensitive and must be stored vacuum-sealed in moisture-barrier aluminum-laminated bags under inert atmosphere (Ar or N2 glovebox). Handling requires a dry environment with dew point below –40 °C, and containers must be resealed promptly after opening to prevent degradation.
LZCO (Li2ZrOCl4) is a halide-oxide hybrid solid-state electrolyte offering ionic conductivity of 1.2–1.6 mS/cm at 28°C, bridging the gap between sulfide-class performance and halide stability for high-voltage cathodes in all-solid-state lithium batteries.
Positive
- High ionic conductivity approaching sulfide levels: With a typical conductivity of 1.55 mS/cm at 28°C, LZCO achieves performance comparable to sulfide electrolytes while retaining halide chemistry advantages, enabling high-power solid-state cell designs.
- Stability against high-voltage cathodes: The halide-oxide hybrid structure provides electrochemical stability compatible with 4 V-class cathodes such as LCO and NCM/Ni83, reducing interfacial degradation in all-solid-state lithium batteries.
Trade-offs
- Moisture-sensitive handling required: LZCO is moisture-sensitive and must be stored and handled in a dry environment with dew point below –40°C, such as an argon or nitrogen glovebox, to prevent degradation.
- Partially amorphous structure variability: The crystal structure is described as partially amorphous, which may introduce batch-to-batch variability in ionic conductivity and mechanical properties, requiring careful quality control for reproducible cell fabrication.
