General description

Ammonium fluoride is a white crystalline solid soluble in water. It adopts the wurtzite crystal structure and forms mixed crystals similar to ice. It is also known for its use as an energetic fluorinating agent and finds application in the field of solar cells and batteries.

Application

Ammonium fluoride can be used:
  • To modify the interface between the electron transport layer and the perovskite layer of solar cells. This helps to reduce interfacial defects and charge recombination enhancing power conversion efficiency of perovskite solar cells (PSCs).
  • As a structure directing agent to prepare electroactive materials for supercapacitors.
  • To synthesize NiF2/porous carbon (NPC) nanocomposite by a bottom-up method for cathodes of Li-ion battery. Heat treatment with NH4F produces a high yield of metal fluoride/porous carbon nanocomposites.

Storage of solar radiation is currently accomplished by coupling two separate devices, one that captures and converts the energy into an electrical impulse (a photovoltaic cell) and another that stores this electrical output (a battery or a supercapacitor electrochemical cell).

Questions

1–2 of 2 Questions  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. 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.

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. 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
