Sigma-Aldrich material aluminum substrate (current collector) Quality Level 100 grade battery grade

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.

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.[1][2] 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.[3]
