Highly Ordered Mesostructured Vanadium Phosphonate toward Electrode Materials for Lithium-Ion Batteries

Journal Article


Abstract


  • Highly ordered mesostructured vanadium phosphonates

    (VP) have been synthesized in the presence of cetyltrimethylammonium

    bromide (CTAB) as a structure-directing

    agent. Nitrilotris(methylene)triphosphonic acid (NMPA)

    and (ammonium/sodium) metavanadate (NH4VO3/NaVO3)

    have been used for the construction of pore walls. The CTAB

    templates are removed from the materials by an extraction

    process without destroying the parent mesostructure. The

    formation mechanism for the ordered mesoporous structure

    and its impact on electrochemical application in lithium ion

    batteries (LIBs) are explained by considering the structural

    and electrochemical stability of the framework. The results

    demonstrate that the counter cations (NH4

    +/Na+) of the

    metavanadate precursors have a crucial role in stabilizing

    the mesoporous structure of the mesoporous VP materials.

    Mesoporous VP materials with highly ordered structure have

    great applicability as high-performance electrode materials

    in LIBs due to the advantages of their large contact area

    with electrolyte and short transport paths for lithium ions.

    Mesoporous VP electrodes exhibit high reversible specific capacity

    with superb cycling stability (100 cycles) and excellent

    retention of capacity (92%).
