  • Mixed Lithium/Sodium Ion Iron Fluorophosphate Cathodes for Lithium Ion Batteries
    Publication number: 20080153002
    Abstract: A compound having the formula LiaNa2?aFePO4F, wherein 0<a?2 may be synthesized by exchanging lithium ions for sodium ions in Na2FePO4F. The compound may be used as a cathode material for a lithium ion battery. A battery may be comprised of an electrode active material having the formula Li2FePO4F, an anode; and an electrolyte. Na2FePO4F may be synthesized by flux reaction. Microcrystalline Na2FePO4F may be synthesized by a solution method. Na2FePO4F may be used as a cathode material for a lithium ion battery and may be carbon composite coated.
