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
- An electrolyte additives to improve the cycling efficiency of lithium and graphite anodes in lithium-ion batteries. The cesium cations can help control the interfacial chemistry on the anode, leading to enhanced performance.
- An additive to enhance the efficiency and stability of CsPbI2Br perovskite solar cells by passivating defects, improving charge transport properties, and contributing to higher power conversion efficiencies.
- As a precursor material to synthesize cesium lead bromide (CsPbBr3) perovskite, which is then utilized as an electrode material in a symmetric supercapacitor.
- As a precursor to prepare thermal neutron imaging plates.
- As a precursor to synthesize lead-free CsBr: Eu2+ nanocrystals for fabricating white LEDs.
- As an additive to prepare CsI-based scintillators. Alloying with cesium bromide increases the yield limit and microhardness of CsI crystals.

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
