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.

General description
Application
- As an additive to fabricate SiO@C/graphite composite anode materials for Li-ion batteries. LiF stabilizes solid electrolyte interphase (SEI) and enhances initial coulombic efficiency.[1]
- As a critical component in SEI for stabilizing the SEI layer and improving the cycling efficiency of Li metal batteries.[3]
- To fabricate electron contacts for high-efficiency n-type crystalline silicon solar cells.[2]
- To prepare solid-state light sources for radiation imaging detectors.[4]
- To synthesize highly crystalline MXene for asymmetric supercapacitor applications. And also, lightweight, flexible, and hydrophobic MXene foam with reasonable strength, high electrical conductivity, and an outstanding EMI-shielding performance.[5]
- As an electron-injection layer to fabricate ITO/PEDOT:PSS/perovskite/B3PYMPM/ LiF/Al OLED device with a quantum efficiency of 20%.[6]

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
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
