NEI Corporation is excited to introduce a new sulfide-based solid electrolyte material: Chlorine-rich Lithium Phosphorus Sulfur Chloride (Li_5.5PS_4.5Cl_1.5). It belongs to the argyrodite family of compounds and is a promising solid electrolyte material for all-solid-state lithium-ion batteries. Some key properties and benefits include:

• High ionic Conductivity: Cl-rich LPSCl exhibits exceptionally high ionic conductivity for lithium ions, comparable to that of liquid electrolytes. This enables faster charging and discharging rates in batteries.
• Wide Electrochemical Window: The material has a stable operating voltage window, allowing for the use of higher-voltage cathode materials and increased energy density.
• Improved Stability: The addition of chlorine to the Li-P-S framework enhances the stability of the electrolyte, reducing interfacial reactions with electrodes and improving overall battery performance.
• Safety: As a solid electrolyte, Li_5.5PS_4.5Cl_1.5 eliminates the risk of electrolyte leakage and flammability, making batteries safer.

Product Specifications:

• Formula: TiNb₂O₇
• Color: Light brown, beige
• Molecular Weight: 266.625 g/mole
• Crystal Structure: Argyrodite
• Crystal Density: 1.64 g/cm3
• Ionic Conductivity: 3 to 5 x 10^-3 S/cm (unsintered, cold-pressed pellet @ RT)
