If you need more than 200 grams, please contact Ampcera Inc. (info@ampcera.com) directly for bulk pricing.

Manufacturer: Ampcera Inc.

Product Number: PO0184

Composition: : Li₆PS₅Cl_0.5Br_0.5

Material Type: Argyrodite, Li-argyrodite crystalline phase

Purity: synthesized from >99.9% precursor materials

Product Form: light yellow color powder

Particle Size: Pass 325 mesh, D50 ~ 10 µm. This fine powder can be directly used to make composite solid electrolytes or to mix with cathode materials as solid state catholyte. The finer powder helps to improve the cathode-electrolyte interface contact.

Ionic Conductivity: up to > 3.5 x 10^-3 S/cm (3.5 mS/cm) at room temperature, the ionic conductivity is slightly lower compared to the coarse powder due to the effect of more interfaces among the fine particles.

Electronic Conductivity: ~10^-6 S/cm at room temperature (25 degree C)

Applications: Solid state electrolyte material for all solid state lithium ion batteries. Cathode electrolyte (catholyte).

Storage and Cautions: Water sensitive. Store and operate in a dry environment.

About Argyrodite solid electrolyte:

Argyrodites, Li₆PS₅X (X = Cl, Br), are considered to be among the most promising solid-state electrolytes for solid-state batteries. Argyrodite-type crystalline materials, such as Li₆PS₅Cl_0.5Br_0.5, are promising solid electrolytes for all-solid-state lithium-ion batteries because of their high ionic conductivity (up to > 3.5 mS/cm at room temperature), good processability and excellent electrochemical stability. Li₆PS₅Cl_0.5Br_0.5 has been reported to exhibit higher ionic conductivity than Li₆PS₅Cl and Li₆PS₅Br. With its proprietary technology, Ampcera Inc. is the first company in the world that has successfully commercialized the Argyrodite-type Li₆PS₅Cl_0.5Br_0.5solid electrolyte material with a production capacity of more than one metric ton per year.
