General description

Our lithium iron phosphate (LFP) electrode sheet is a ready-to-use cathode for lithium-ion battery research. The LFP cathode film is cast 70 µm thick, single-sided, on a 16 µm thick aluminum foil current collector that is 5 × 10 inches (127 mm × 254 mm) in size. The composition is 88% lithium iron phosphate (LFP), 4% Poly(vinylidene fluoride) [PVDF] and 8% carbon black. The active material, olivine LiFePO4, is a well-studied cathode material, known for its excellent cycling stability.
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 information.

Application

The primary application of our lithium iron phosphate (LFP) electrode is as a cathode in lithium-ion battery research. LFP is inexpensive, nontoxic, cobalt-free, and environmentally benign. It achieves high specific capacity (>150 mAh/g) and offers a considerably longer cycle life than other lithium-ion chemistries. LFP cells experience a slower rate of capacity loss and greater calendar-life than lithium-ion battery chemistries such as cobalt (LiCoO2), manganese spinel (LiMn2O4), lithium-ion polymer batteries (LiPo battery), and nickel-based lithium-ion cathodes. Because of its low-cost, low-toxicity, long-term stability, and well-defined performance, LFP-based batteries are finding roles in vehicle use and backup power applications.
