Name: LIC Halide Solid-State Electrolyte (Li₃InCl₆)
Material Form: Powder (two particle size grades available)
Product Code: XN-LIC
Description:
LIC (Li₃InCl₆) is a high-performance indium-based halide solid-state electrolyte for all-solid-state battery (ASSB) research. As one of the most widely studied chloride electrolytes in academic literature, LIC delivers excellent room-temperature ionic conductivity (1.0–1.4 mS/cm), strong electrochemical stability against high-voltage oxide cathodes, and significantly better moisture tolerance than sulfide electrolytes (LGPS, LPSC). Furthermore, the material is cold-pressable, simplifying ASSB cell assembly. As a result, LIC is a leading candidate for oxide-cathode-based ASSB systems.
Application:
This material serves as a high-conductivity catholyte for all-solid-state lithium batteries with high-voltage oxide cathodes (NCM, LCO, high-nickel systems). Additionally, it is widely used in halide electrolyte fundamental studies, sulfide-halide composite electrolyte architectures (paired with LPSC as anode-side separator), and solid-state pouch cell prototyping.

Characteristics:
High room-temperature ionic conductivity
The coarse grade delivers >1.4 mS/cm and the fine grade >1.0 mS/cm at 27 °C — among the highest in the chloride halide electrolyte family. Moreover, the negligible electronic conductivity (<10⁻⁸ S/cm) prevents internal short-circuiting in finished cells.
High-voltage cathode compatibility
Halide chemistry is intrinsically stable against 4 V-class cathodes including NCM, LCO, and high-nickel systems. Therefore, no LiNbO₃ or other interface coatings are required, simplifying cell architecture and reducing cathode interface resistance.
Better moisture tolerance than sulfides
Compared with sulfide electrolytes (LGPS, LPSC), LIC tolerates brief ambient exposure significantly better. Consequently, this lowers the bar for laboratory handling and reduces process complexity in pilot-scale manufacturing.
Cold-pressable for easy ASSB cell assembly
The material can be densified at room temperature without high-temperature sintering. As a result, customers can quickly fabricate coin cells and pellet cells without specialized hot-pressing equipment.
Two particle size grades for flexibility
Choose the coarse grade (>5 μm, higher conductivity) for maximum performance, or the fine grade (<1 μm, larger surface area) for better catholyte mixing and cathode interface contact in composite electrode formulations.
Packaging & Storage:
The material ships vacuum-sealed under inert atmosphere. Therefore, customers should store sealed in an Ar or N₂ glovebox, protected from moisture. Reseal promptly after opening. Standard pack sizes range from 10 g samples to 500 g; larger custom quantities are available on request.
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. Compare with our other halide electrolytes: LNOC (LiNbOCl₄) at ~7 mS/cm, LZCO (Li₂ZrOCl₄) at 1.55 mS/cm, Al-Doped LZC at 0.7 mS/cm, LZC (Li₂ZrCl₆) at 0.3 mS/cm, and LYC (Li₃YCl₆) at 0.3–0.4 mS/cm.
