Self-Assembly of the Mesoporous Electrode Material Li3Fe2 (PO4) 3 Using a Cationic Surfactant as the Template

Toshikazu Miyoshi, The University of Akron


Mesoporous Li3Fe2(PO4)3 battery electrode materials (see Figure) with a discharge capacity of 140 mAh g–1 at 20 mA g–1 self-assemble under aqueous conditions using a cationic surfactant as the template. Mössbauer spectroscopy results are characteristic of Fe3+ ions in oxides, while the interaction of lithium with Fe and O in mesoporous Li3Fe2-(PO4)3 is verified by 7Li NMR. This synthetic strategy may be applied to the production of other multi-metal phosphate ordered mesoporous structures.
