Name: LZCO Halide-Oxide Solid-State Electrolyte (Li₂ZrOCl₄)
Material Form: Powder
Product Code: XN-LZCO
Description:
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. LZCO represents the highest-conductivity option in Xnergy’s LZC product family, ideal for high-power and high-loading ASSLB applications.
Application:
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.

Characteristics:
Highest conductivity in the LZC family
1.2–1.6 mS/cm at 28 °C — roughly 5× higher than pure Li₂ZrCl₆ (0.3 mS/cm) and 2× higher than Al-doped LZC (0.7 mS/cm). Approaches sulfide electrolyte performance while retaining halide-class oxidative stability.
High-voltage cathode compatibility
Halide-oxide chemistry is intrinsically stable against 4 V-class cathodes (LCO, Ni83). No LiNbO₃ or other interface coatings required, simplifying cell architecture and reducing cathode interface resistance.
Validated in full ASSLB cells
LCO|LZCO|LPSC|Li-In: ~160 mAh/g, 97.07% coulombic efficiency. Ni83|LZCO|LPSC|Li-In: ~195 mAh/g, 87.45% coulombic efficiency. Both at 7 mg/cm² loading, 28 °C.
Hybrid halide-oxide architecture
Oxygen substitution in the Li₂ZrCl₆ framework optimizes the lithium migration pathway, delivering practical ionic conductivity for high-power and high-loading solid-state applications.

Packaging & Storage:
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.
Safety:
For research and industrial use only. Wear PPE (gloves, masks, safety goggles). Refer to SDS for complete safety information.
Note: Values listed above are typical and for reference only. Performance may vary depending on cell architecture, cathode selection, electrolyte separator, and test protocol.
