LiTaOCl4 (LTOC) is a lithium-lean tantalum-based oxychloride solid-state electrolyte engineered for next-generation high-voltage all-solid-state lithium batteries (ASSLBs). Combining the high ionic conductivity of chloride electrolytes with the moisture stability benefits of oxide components, this composition delivers 6–8 mS/cm room-temperature ionic conductivity along with strong electrochemical stability against high-voltage cathodes. Furthermore, LiTaOCl5 offers an alternative stoichiometry to Li2TaOCl5 for studies requiring different lithium-content optimization.
| Parameter | Detail |
|---|---|
| Chemical formula | LiTaOCl4 |
| Ionic conductivity | 6–8 mS/cm @ 28 °C |
| Crystal structure | Tantalum oxychloride framework |
| Electrochemical window | Stable vs high-voltage cathodes |
This material serves as a high-conductivity catholyte for all-solid-state lithium batteries with high-voltage cathodes (LCO, NCM, Ni83). Especially suitable for sulfide-halide composite electrolyte architectures (paired with LPSC as anode-side separator), oxychloride electrolyte chemistry studies, room-temperature ASSB prototyping, and fundamental research on lithium-content effects in tantalum oxychlorides.
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. Larger custom quantities are available on request. While the material offers better moisture tolerance than sulfides, brief air exposure should still be avoided to preserve ionic conductivity.
For research and industrial use only. Wear PPE (gloves, masks, safety goggles). Refer to SDS for complete safety information.

LiTaOCl₄ is a moisture-sensitive lithium tantalum oxychloride solid electrolyte that requires inert atmosphere storage to prevent degradation. All handling must be performed in an argon or nitrogen glovebox while wearing appropriate personal protective equipment.
- Storage Atmosphere: Store the material sealed in an argon or nitrogen glovebox to prevent moisture degradation.
- Moisture Sensitivity: Avoid any air exposure to preserve ionic conductivity; the material is shipped vacuum-sealed in moisture-barrier bags.
- PPE Requirement: Wear gloves, safety goggles, and a mask when handling the material.
- Containment: Keep the material in its original sealed bag until transferred to the glovebox.
This procedure describes the safe transfer, weighing, and storage of LiTaOCl₄ powder under inert conditions. Following these steps preserves ionic conductivity and minimizes exposure hazards.
Required Equipment: Argon glovebox, Spatula, Analytical balance, Sealed storage container
- Don PPE
Don appropriate PPE including gloves, mask, and safety goggles before handling the material. - Transfer to glovebox
Transfer the vacuum-sealed bag into an argon-filled glovebox without opening. - Open bag
Open the bag only inside the glovebox to avoid moisture exposure. - Weigh powder
Weigh the required amount of powder using a clean spatula and balance. - Seal remainder
Seal the remaining material in a moisture-proof container within the glovebox.
How does the moisture stability of LiTaOCl4 compare to sulfide solid electrolytes, and does it require glovebox handling?
LiTaOCl4 offers better moisture tolerance than sulfide solid electrolytes due to its oxychloride framework, but brief air exposure should still be avoided to preserve ionic conductivity. The product ships vacuum-sealed under inert atmosphere and must be stored sealed in an Ar or N2 glovebox protected from moisture.
Can LiTaOCl4 be integrated into composite electrolyte architectures with LPSC as the anode-side separator?
Yes, LiTaOCl4 is explicitly designed for sulfide-halide composite electrolyte architectures paired with LPSC (Li6PS5Cl) as the anode-side separator. The product description recommends this configuration for all-solid-state lithium batteries with high-voltage cathodes such as LCO, NCM, and Ni83.
What is the purpose of the LiTaOCl5 alternative stoichiometry offered alongside LiTaOCl4?
The LiTaOCl5 alternative stoichiometry is provided for studies requiring different lithium-content optimization in tantalum oxychloride electrolytes. It enables direct comparison of lithium-content effects on ionic conductivity and electrochemical performance, as noted in the product description.
LiTaOCl4 (LTOC) is a lithium-lean tantalum oxychloride halide solid-state electrolyte offering 6–8 mS/cm ionic conductivity at room temperature and improved moisture stability compared to sulfide electrolytes, making it suitable for high-voltage cathode integration in all-solid-state lithium batteries, though it requires inert atmosphere storage and its lithium-lean composition may necessitate stoichiometric optimization for specific applications.
Positive
- High ionic conductivity for ASSLBs: LiTaOCl4 exhibits 6–8 mS/cm room-temperature ionic conductivity and electrochemical stability against high-voltage cathodes (LCO, NCM, Ni83), enabling efficient catholyte performance in all-solid-state batteries.
- Improved moisture tolerance over sulfides: The oxychloride composition combines chloride conductivity with oxide moisture stability, offering better air tolerance than sulfide electrolytes, though brief air exposure should still be avoided to preserve conductivity.
Trade-offs
- Inert atmosphere storage required: The material must be stored sealed in an Ar or N2 glovebox to protect against moisture; even brief air exposure can degrade ionic conductivity, necessitating proper handling infrastructure.
- Lithium-lean stoichiometry may limit direct application: As a lithium-lean composition, LiTaOCl4 may not be optimal for all cathode or electrolyte pairings; researchers may need to evaluate alternative stoichiometries (e.g., LiTaOCl5) for specific lithium-content optimization.
