Aplicación

Lithium Fluoride (LiF) can be used as an additive in electrolytes for lithium-ion batteries to enhance thermal stability and overall battery performance. Applied as a thin film on electrodes to improve their stability and lifespan by preventing degradation during cycling. LiF is a crucial component of the anode interface film due to its high-modulus shell, which can prevent LixSi pulverization, and its high chemical stability, which effectively suppresses side reactions at the interface. LiF is used in nuclear reactors and radiation detectors due to its low neutron cross-section and ability to capture neutrons, making it suitable for neutron shielding and detection.[1]

Lithium fluoride (LiF) can be used as a sintering aid that facilitates the etching of spinel particles for the degradation of magnesium aluminum spinel.[2] It can be used in the preparation of carbon-iron LiF nanocomposite based electrode materials for lithium-ion batteries.[3] It can also form thin interlayers on the counter electrode to enhance the fill factor and stabilize the high open-circuit voltages for polymer solar cells.[4]

Questions

1–3 of 3 Questions  
  1. 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

  2. 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.
