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
- High electrochemical stability
- High lithium-ion conductivity
- Thermal stability
- Hydrophilic nature
Application
- An additive in the development of dual-functional separator coating materials. These materials are based on covalent organic frameworks (COFs) and are specifically designed for use in high-performance lithium-selenium sulfide batteries. The Li-SeS2 battery achieved outstanding performance in terms of energy storage and stability. It exhibited a specific capacity of 844.6 mA h g-1 at 0.5C and a SeS2 loading of 2 mg cm-2.
- As an additive in the electrolyte formulation along with polyethylene oxide for the development of solid-state lithium batteries. LiTFSI enhance the ionic conductivity of the PEO-based electrolyte, which is essential for the efficient transport of lithium ions.
- As a key component in the development of a PEO/LiTFSI-coated polypropylene membrane. This membrane is designed for high-loading lithium–sulfur batteries to enhance battery performance, improve capacity, and extend cycle life.
- As a component in the electrolyte system along with TEMPOL derivatives. The incorporation of LiTFSI in the electrolyte system enhances the stability and achieves an efficiency of 6.16% in solid-state fiber dye-sensitized solar cells.

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
