一般說明

Lithium hydroxide (LiOH)- anhydrous, 99.9% trace metal basis is a white powder highly soluble in water. Lithium hydroxide is a strong base and can react with acids to form lithium salts and water. Its properties make it useful in a wide range of applications, including battery technology, chemical synthesis, and industrial processes.

應用

Lithium hydroxide (LiOH)- anhydrous, 99.9% trace metal basis has numerous applications across various fields. Its primary use is in battery technology, where it plays a critical role in the production of cathode materials for lithium-ion batteries; particularly lithium cobalt oxide (LiCoO2) and lithium nickel cobalt manganese oxide (LiNiMnCoO2). It enhances the electrochemical performance and stability of these batteries. It is very useful in research areas of next-generation batteries, including lithium-sulfur and solid-state batteries to enhance energy density and extend battery lifespan. LiOH is used as a strong base in various chemical syntheses, facilitating reactions that require alkaline conditions. In the production of ceramics and glass, LiOH is used as a flux to lower the melting point of the raw materials and as an additive to improve the properties of ceramic glazes, such as durability and thermal resistance. LiOH is utilized in CO2 scrubbers to absorb carbon dioxide from the air. This application is particularly important in closed environments such as submarines and spacecraft, where maintaining breathable air is critical.[1][2][3]

特點和優勢

  • Lithium hydroxide (LiOH)- anhydrous is designed for high-end research applications with stringent control of water content and trace metal impurities.
  • Lower content of trace metals especially, B, Ca, Al, Sr, K, and Na contribute to enhanced performance.

Questions

1–3 of 3 Questions  

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

    1 answer

    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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

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

    1 answer

    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. What is this chemical KST value

    1 answer

    1. The Safety Data Sheet (SDS) for Product No. 920312 (Lithium hydroxide, anhydrous, 99.9% trace metals basis) states in Section 9 that the material is not classified as an explosive material. It does not have a measured explosion index (Kst) value.
