일반 설명

Battery-grade Al-doped Lithium Lanthanum Zirconate Oxide (LLZO) powder is a high-purity, inorganic material that is specifically designed for use in advanced battery applications. It is a white, crystalline powder with an average particle size of 5-6 microns and is composed of lithium, lanthanum, zirconium, oxygen, and a small amount of aluminum dopant. This material is known for its high ionic conductivity, which falls within the range of 0.01-0.1 mS/cm, making it an ideal electrolyte material for use in solid-state lithium-ion batteries. Moreover, the high purity and narrow particle size distribution of this powder make it well-suited for use in the precise and reproducible manufacturing of battery components.

애플리케이션

The primary application of Al-doped LLZO powder is in all-solid-state and hybrid electrolytes for lithium-ion batteries. The unique combination of properties, including its high lithium-ion conductivity, robust chemical stability, and wide electrochemical stability window, make it a promising candidate for the next generation of solid-state batteries. This material has the potential to replace the conventional liquid electrolyte in lithium-ion batteries, offering higher energy density, improved safety, and longer lifespan.

특징 및 장점

Our LLZO powder provides high ionic conductivity and consistent particle size for reproducible results.
  • Improved Battery Safety
  • Increased Energy Density

질문

1–3 / 3 질문  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 답변

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 답변

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

  3. How many Al percentage is in the powder?

    1 답변

    1. The Aluminum content of this material is not tested. However, based on the molecular formula of Li6.24 La3 Zr2 Al0.24 O11.98, the Al content may be calculated by using the following equation:

      27 (atomic weight of Al) x 0.24 / (7 x 6.24 + 139 x 3 +91 x 2 + 27 x 0.24 + 16 x 11.98) (Mw of Li6.24La3Zr2Al0.24O11.98) = 6.48 / (43.68 + 417 +182 + 6.48 +191.68) = 6.48 / 840.84 = 0.0077.

      Therefore, the theoretical percentage of Aluminum is 0.77 %.
