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
- To prepare biodegradable polymer electrolytes.Rice starch complexed with LiI shows enhanced ionic conductivity as theaddition of LiI increases the number of mobile charge carriers.
- For Li-S batteries. LiIforms a protective coating on the surface of both negative and positiveelectrodes and prevents the dissolution of polysulfides on the cathode sidewhich significantly enhances cell rate performance.
Features and Benefits
- 10 mesh particle size provides a larger surface area for better reactivity and interaction in chemical processes, improving efficiency in energy storage and conversion.
- 99.9% trace metals purity facilities better charge/ion transport leading to improved performances.
- Enhances durability and Longevity of energy & electronic devices due to minimum metal impurities.
- Low metal impurities reduce structural defects in solar cells and contribute to the formation of a stable electrolyte in batteries.

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
