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
Liquid electrolyte solutions play a key role in lithium ion batteries (LIB) acting as a carrier of lithium ions between the cathode and anode. High-purity and battery-grade electrolyte solutions are thus crucial for lithium ion battery performance. The most common LIB electrolytes are derived from solutions of lithium salt, such as LiPF6 in non-aqueous solvents, example alkyl carbonates or solvent blend. The choice of the electrolyte solution is dependent on both the operating conditions like temperature and the nature of the electrode material in the LIB. The performance of the electrolyte solutions can be further modified with appropriate additives.
Other Notes
- Do not use with glass equipment
- All work should be done very quickly under dry air to prevent electrolytes from water uptake and solvent vaporization.

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
