## Description

- description: "We investigate spinel-type MgV2O4 (MVO) as a cathode material and
    elucidate the correlation between its crystal structure and electrochemical performance.
    An ordered spinel was synthesized via a solid-state route and subsequently subjected
    to mechanical milling (MM), while a solvothermal (ST) method was employed to prepare
    a comparative sample. Rietveld refinement revealed that MM induces a transition
    from an ordered to a disordered spinel structure, accompanied by partial V occupancy
    at the interstitial 16c site, which obstructs Mg2+ migration between 8a sites.
    Despite particle size reduction, MM-MVO exhibited poor reversibility due to\r\nthis
    structural disorder. Complementary computational analysis confirmed the energetic
    favorability of V migration into the 16c site by MM, explaining the origin of
    the diffusion barrier. In contrast, ST-MVO retained a relatively ordered structure
    with minimal V occupation at 16c sites and delivered a reversible capacity of
    175 mAh g−1 at 2 V when paired with a high-voltage electrolyte. These findings
    highlight the critical role of spinel ordering in enabling efficient Mg2+ transport
    and provide design guidelines for high performance MRB cathodes."
