Name: O-Doped LZC Solid-State Electrolyte (Li₂ZrCl₆-Oₓ)
Material Form: Powder
Product Code: XN-O-LZC
Description:
O-Doped LZC (Li₂ZrCl₆-Oₓ) is an oxygen-doped chloride halide solid-state electrolyte engineered for high-performance all-solid-state lithium batteries (ASSLBs). Oxygen substitution into the Li₂ZrCl₆ lattice optimizes the lithium migration pathway, boosting room-temperature ionic conductivity to 1.2–1.6 mS/cm — roughly 5× higher than pure Li₂ZrCl₆. Furthermore, the material retains halide chemistry’s intrinsic stability against high-voltage cathodes, making it a strong choice for high-power ASSLB applications.
Application:
This material serves as a high-conductivity catholyte for all-solid-state lithium batteries. It is 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, and pouch cell prototyping.

Characteristics:
Significantly enhanced conductivity vs pure LZC
At 1.55 mS/cm at 28 °C, oxygen doping delivers approximately 5× the ionic conductivity of pure Li₂ZrCl₆ (~0.3 mS/cm). Moreover, this also exceeds Al-doped LZC (~0.7 mS/cm), reaching the practical range for high-power solid-state battery applications.
High-voltage cathode compatibility
The chloride-based halide chemistry remains intrinsically stable against 4 V-class cathodes (LCO, Ni83). Therefore, no LiNbO₃ or other interface coatings are required, simplifying cell architecture and reducing cathode interface resistance.
Validated in full ASSLB cells
In LCO|LZCO|LPSC|Li-In configuration, the cell delivers ~160 mAh/g at 97.07% coulombic efficiency. Similarly, Ni83|LZCO|LPSC|Li-In achieves ~195 mAh/g at 87.45% coulombic efficiency. Both tested at 7 mg/cm² loading, 28 °C.
Optimized for solid-state composite architectures
Because of its high conductivity and oxidative stability, the material is well-suited for use as a catholyte in bilayer ASSLB cells where sulfide LPSC serves as the anode-side separator.

Packaging & Storage:
The material ships vacuum-sealed under inert atmosphere in moisture-barrier aluminum-laminated bags. Therefore, customers should store it sealed in Ar or N₂ glovebox, protected from moisture. Because O-doped LZC is moisture-sensitive, handle exclusively in a 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.
