LNOC (LiNbOCl₄) is a niobium-based halide-oxide solid-state electrolyte engineered for next-generation high-voltage all-solid-state lithium batteries (ASSLBs). With ~7 mS/cm room-temperature ionic conductivity and stability up to 4.6 V vs Li/Li⁺, this material delivers performance that exceeds both conventional halide and sulfide electrolytes. As a result, LNOC enables direct compatibility with high-voltage LCO (4.6 V) and high-nickel NCM cathodes for maximum energy density.

This material serves as a high-conductivity, high-voltage catholyte for all-solid-state lithium batteries. Especially suitable for 4.6 V LCO ASSLB cells, high-nickel NCM/Ni83 systems, and sulfide-halide composite electrolyte architectures (paired with LPSC as anode-side separator). Additionally, it works well in high-power solid-state pouch cells and pilot-scale ASSLB manufacturing.
The material ships vacuum-sealed under inert atmosphere in moisture-barrier aluminum-laminated bags. Therefore, customers should store sealed in Ar or N₂ glovebox, protected from moisture. Because LNOC is moisture-sensitive, handle exclusively in a dry environment with dew point < –40 °C. Reseal promptly after opening.
For research and industrial use only. Wear PPE (gloves, masks, safety goggles). Refer to SDS for complete safety information.

LNOC is moisture-sensitive and must be handled exclusively in a dry environment with dew point below –40 °C. Store the material sealed in an argon or nitrogen glovebox to prevent degradation from atmospheric moisture.
- Moisture Sensitivity: Exposure to atmospheric moisture degrades the ionic conductivity and electrochemical performance of LNOC.
- Glovebox Storage: All storage and handling must be performed inside an argon or nitrogen glovebox with controlled inert atmosphere.
- Dew Point Requirement: The handling environment must maintain a dew point below –40 °C to avoid moisture-induced degradation.
- Post-Opening Sealing: Reseal the vacuum-sealed bag immediately after each use to minimize moisture ingress.
Can LNOC be used directly with high-voltage LCO cathodes without additional coating?
Yes, LNOC is engineered for direct compatibility with high-voltage LCO cathodes up to 4.6 V vs Li/Li⁺, as well as high-nickel NCM (Ni83) systems. Its electrochemical stability window of 4.6 V and ionic conductivity of ~7 mS/cm at 28 °C eliminate the need for additional protective coatings in these configurations.
What cathode materials and battery architectures are compatible with LNOC in all-solid-state batteries?
LNOC is compatible with 4.6 V LCO and high-nickel NCM/Ni83 cathodes. It can also be used in sulfide-halide composite electrolyte architectures, where it is paired with LPSC as an anode-side separator, making it suitable for high-power pouch cells and pilot-scale ASSLB manufacturing.
What are the storage and handling requirements for LNOC due to its moisture sensitivity?
LNOC is moisture-sensitive and must be stored in an Ar or N₂ glovebox with a dew point below –40 °C. The material ships vacuum-sealed in moisture-barrier aluminum-laminated bags and should be handled exclusively in a dry environment, with the bag resealed promptly after opening.
LiNbOCl4 (LNOC) is a niobium-based halide-oxide solid electrolyte offering ~7 mS/cm ionic conductivity at 28°C and electrochemical stability up to 4.6 V vs Li/Li⁺, enabling direct pairing with high-voltage LCO and NCM cathodes in all-solid-state lithium batteries. Its partially amorphous niobium halide-oxide framework and low activation energy (0.256 eV) support high-power operation, but the material requires strict inert-atmosphere handling due to moisture sensitivity.
Positive
- High ionic conductivity at room temperature: With ~7 mS/cm at 28°C, LNOC exceeds typical halide and sulfide electrolytes, enabling high-rate capability in all-solid-state cells.
- Wide electrochemical stability window: Stable up to 4.6 V vs Li/Li⁺, LNOC is directly compatible with high-voltage cathodes such as 4.6 V LCO and high-nickel NCM, maximizing cell energy density.
Trade-offs
- Moisture-sensitive handling required: LNOC is moisture-sensitive and must be stored and handled exclusively in an inert atmosphere (Ar or N₂ glovebox) with dew point below –40°C to prevent degradation.
- Partially amorphous structure variability: The material's partially amorphous niobium halide-oxide framework may introduce batch-to-batch consistency challenges in crystallinity, affecting ionic transport reproducibility.
