Mixed Lithium/Sodium Ion Iron Fluorophosphate Cathodes for Lithium Ion Batteries |
| 摘要 |
A compound having the formula Li<SUB>a</SUB>Na<SUB>2-a</SUB>FePO<SUB>4</SUB>F, wherein 0<a<=2 may be synthesized by exchanging lithium ions for sodium ions in Na<SUB>2</SUB>FePO<SUB>4</SUB>F. 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 Li<SUB>2</SUB>FePO<SUB>4</SUB>F, an anode; and an electrolyte. Na<SUB>2</SUB>FePO<SUB>4</SUB>F may be synthesized by flux reaction. Microcrystalline Na<SUB>2</SUB>FePO<SUB>4</SUB>F may be synthesized by a solution method. Na<SUB>2</SUB>FePO<SUB>4</SUB>F may be used as a cathode material for a lithium ion battery and may be carbon composite coated.
