Descrição geral

Lithium iron(II) phosphate (LiFePO4), also called LFP, is a crystalline, grey-to-black powder with an olivine crystal structure. This unique structure facilitates efficient diffusion of lithium-ions, thanks to the three-dimensional interconnected iron phosphate tetrahedra that form pathways for lithium ions to diffuse. Additionally, the structure is highly stable, not deforming, even after thousands of cycles of lithium intercalation. Our LiFePO4 powder is manufactured to meet high purity with a tightly controlled particle size of less than 5 μm.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Click here for more details.

Aplicação

LiFePO4 is a widely used cathode for rechargeable Li batteries. It has high energy density, wide operating temperature, thermal stability, long cycle life and application life, environmental friendliness, and safety that make it a promising electrode material for greener and safer lithium-ion batteries.[1][2][3]

Características e benefícios

LiFePO4-based batteries can last longer, operate safely and reliably, and power devices in a wide range of temperatures.
✔ Achieves 1000s of cycles
✔ Safer than cobalt or manganese-based cathode materials
✔ Reliable performance

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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

  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
