Name: Al-Doped LZC Solid-State Electrolyte (Li₂.₂₅Zr₀.₇₅Cl₆Al₀.₂₅)
Material Form: Crystalline powder
Product Code: XN-3Al-LZC
Description:
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.
Application:
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.

Characteristics:
High-voltage cathode compatibility
Halide chemistry is intrinsically stable against 4 V-class cathodes (LCO, Ni83). No LiNbO₃ or other interface coatings required, simplifying cell architecture.
Practical room-temperature conductivity
0.7 mS/cm at 28 °C on a 1.2 mm pellet — sufficient for room-temperature ASSLB operation without elevated-temperature testing.
Validated in full ASSLB cells
LCO|3Al-LZC|LPSC|Li-In: 160 mAh/g, 98.1% coulombic efficiency. Ni83|3Al-LZC|LPSC|Li-In: >200 mAh/g, 89.67% coulombic efficiency. Both at 7 mg/cm² loading, 28 °C.
Cost competitiveness
Zirconium-based halide chemistry offers a lower-cost alternative to yttrium-based halide electrolytes (Li₃YCl₆) at comparable conductivity.
Performance Data:
Packaging & Storage:
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.
Safety:
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.
Note: Values listed above are typical and for reference only. Performance may vary depending on cell architecture, cathode selection, electrolyte separator, slurry processing, electrode loading, calendering pressure, and test protocol.
