一般描述

氟化锂是一种无机卤化物,具有良好的离子导电性、紫外区的高折射率和高透过率。由于其独特的性质,它被广泛应用于光电设备、X射线成像和牙科材料领域。[1] [2]

应用

氟化锂(LiF)可用于:
  • 制造交流驱动有机发光二极管 (OLED)中的绝缘层。LiF为交流设备中的绝缘层带来良好的电容 和高稳定性。[1]
  • 作为溶剂热法合成Eu2+/Ce3+ 掺杂氟化锂钡磷光体的前体。[2]
  • 制造锂阳极上的LiF薄膜涂层 以增强其稳定性和库仑效率。[3]
  • 作为添加剂用于富集和增强锂金属电池中固相电解质界面(SEI)的性能。[4]

Professor Gogotsi and Dr. Shuck introduce MXenes: a promising family of two-dimensional materials with a unique combination of high conductivity, hydrophilicity, and extensive tunability.

Solid-state lithium fast-ion conductors are crucial for safer, high-energy-density all-solid-state batteries, addressing conventional battery limitations.

Questions

1–2 of 2 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.

  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
